Peter Pett's Commentary on the Bible
Isaiah 6:5-13
Yahweh's Call To Isaiah (Isaiah 6:5).
As Isaiah stood, or possibly prostrated himself, before the wonderful vision of resplendent holiness, it was all too much for him as he was made aware of his own sinfulness. But God arranged for his cleansing preparatory to calling him to the task that he has in store for him, the proclaiming of God's message to an ungrateful people, with the promise that it would finally result in a holy seed.
Analysis of Isaiah 6:5.
a Then I said, “Woe is me, for I am undone, because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips, for my eyes have seen the King, Yahweh of Hosts (Isaiah 6:5).
b Then flew one of the seraphim to me, having a live coal in his hand, which he had taken with the tongs from off the altar, and he touched my mouth with it, and said, “Lo, this has touched your lips, and your iniquity is taken away, and your sin is purged” (Isaiah 6:6).
c And I heard the voice of the Lord, saying, “Whom shall I send, and who will go for us?” Then I said, “Here I am. Send me” (Isaiah 6:8).
c And He said, “Go, and tell this people, ‘Hear you indeed, but do not understand, and see you indeed, but do not perceive.' Make the heart of this people fat, and make their ears heavy, and shut their eyes, lest they see with their eyes, and hear with their ears, and understand with their heart, and turn again and be healed” (Isaiah 6:9).
b Then I said, “Lord, how long?” And He answered, “Until the cities be waste without inhabitant, and houses without man, and the land become utterly waste, and Yahweh has removed men far away, and the forsaken places be many in the midst of the land (Isaiah 6:11).
a And if there be yet a tenth in it, it will again be eaten up. As a terebinth and as an oak whose stump remains when they are felled, so the holy seed is its stump” (Isaiah 6:13).
In ‘a' we have the sense of the uncleanness of this holy man, who was separated to God and seeing the King, and in the parallel we have a description of the ‘holy seed' who will survive as those who are separated to God. In ‘b' we have the description of how God cleanses His messenger, and in the parallel how He will go about the process of cleansing the land. In ‘c' we have Isaiah's response to the call of God, and in the parallel what it will involve in heartache and disappointment
‘Then I said, “Woe is me, for I am undone, because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips, for my eyes have seen the King, Yahweh of Hosts.” '
Isaiah's response is one of terror, and awareness of his own total unworthiness. Like Job he saw himself as totally unfitted to see God, and unfit for His presence. We have here a parallel thought to that of Job, ‘Now my eye sees you for which reason I abhor myself and repent in sackcloth and ashes' (Job 41:5).
‘Woe me.' Woe was the word that supremely declared the deserts of those who came under God's anger, and later Isaiah would declare God's woes on those whose behaviour angered God (Isaiah 5:11). But at this time he sees that woe as directed against himself. Indeed it is only because he has seen this that he can be permitted to declare God's woe on others. For the man of God does not stand as judge, he stands as one of the accused who has found mercy, speaking on behalf of the Judge. And at this moment Isaiah could see no hope for himself at all.
In the previous chapter we have seen God's six woes declared. Are we to see in this the seventh woe in the series? Isaiah's recognition that he too is subject to woe?
‘For I am undone (destroyed, ruined).' As a result of what he was experiencing he could only visualise disaster for himself. He was devastated in the fullest sense. He was appalled at his own state. For he recognised that only one thing was now fitting, his own total destruction. All hope that he had had of being a minister to God's people was now come to an end. The word ‘undone' contains within it the idea of being silenced by disaster, sorrow or death, and by all that is most devastating.
‘Because I am a man of unclean lips.' Here was the cause of his ruin, for what a man is, is revealed through his lips (Matthew 12:37). And he knew that his lips were not worthy to say ‘holy, holy, holy'. Rather they were only fit to be silenced and doomed. They demonstrated him as fitted for destruction. With them he had sworn fealty to Yahweh. But with them he had also spoken that which was contrary to all that Yahweh is. Thus they were ‘unclean', barred from God's presence, not fitted to speak of God, excluded from referring to holy things. Approach to God was totally out of the question. Like the dying king he could only wait for the death that he deserved. He was a spiritual leper.
Such an experience of awareness of sinfulness, of self-abhorrence, of feeling totally unworthy can be the experience of every godly person in times of spiritual exaltation, although possibly not in the intensity with which it struck Isaiah, because as we become aware of the glory and holiness of God it contrasts with what we ourselves are. For in ourselves we too are often people ‘of unclean lips', saying but not doing, and when we come into the presence of God it can make us very much aware of it. But thankfully there is for us too a ‘burning coal' that contains within it all the essence of sacrifice, for ‘if we walk in the light as He is in the light --- the blood of Jesus His Son cleanses us from all sin --- if we openly admit our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness' (1 John 1:7; 1 John 1:9).
‘And I dwell in the midst of a people of unclean lips.' He knew also that what was true for him was also true for his people. They also were without hope. They were excluded from God. They were no longer the people of the covenant, a prospective holy nation. They were rather under sentence. And any hopes that he had entertained of being God's representative to them were now gone. For he knew that he was not fit, and that they were not fit. They were unclean. They had proved unfaithful to the sworn covenant, the covenant which their lips had sealed but their lives had denied. Their sins and their iniquities had thus totally separated them from God.
With their mouths they had sought or declared what was unjust, voiding justice, they had lied and deceived in life and business, they had encouraged lust or expressed it, they had arranged theft, and even encouraged murder, they had expressed envy, they had revealed hatred, they had dishonoured the Sabbath, and above all they had treated God lightly in the way that they maintained the cult, going about their activity apathetically, and even denying Him by giving to their idols the honour due only to Him. They were utterly unclean. All this has been expressed in Chapter s 1-5 preparatory for these words.
The words bring new meaning to the words ‘in the year that King Uzziah (the isolated leper king) died'. He was dying an isolated leper. And now Isaiah was aware that he himself was spiritually a leper, and that the people too were lepers, and thus isolated from God, and that they too were worthy only to die as the king had died, repulsive and spurned.
‘For my eyes have seen the King, Yahweh of Hosts.” ' And this was because his eyes had seen the King, Yahweh of Hosts. And yet not his eyes only. It had pierced into his heart and his whole moral being. For the first time he had seen Who and What God really is. And once he had seen Him all else was unworthy, and nothing more so than sinful, disobedient man. Note that it is as ‘the King, Yahweh of hosts' that he speaks of God (compare Deuteronomy 33:5). Splendid, glorious, all-powerful, The One Who on Sinai had adopted His people for Himself and declared Himself Overlord over their hosts. Here was the One with Whom Israel had confirmed covenant, and Whom they had subsequently so miserably neglected and spurned. No wonder that he did not feel that his lips were clean enough to swear fealty to such a One. And it was from this vision that would be born his favourite title for God, ‘the Holy One of Israel'.
We too may have made many promises to God in the past, especially in times of crisis. But deeply mistaken, are the ones who can say that they have fully kept them all. For ‘all have sinned and come short of the glory of the Holy One' (Romans 3:23). And we too must thus cry out in the presence of the Holy One, ‘I deserve woe. I have broken my promises. I have not loved Him as I should. I am unclean.'
‘Then flew one of the seraphim to me, having a live coal in his hand, which he had taken with the tongs from off the altar, and he touched my mouth with it, and said, “Lo, this has touched your lips, and your iniquity is taken away, and your sin is purged.” '
‘Then', as Isaiah watched in total despair, he saw one of the seraphim fly to the altar and, with the holy tongs, pick up a live coal from the altar, from among the coals on which the blood of many sacrifices had fallen. And as he watched the seraph flew to him and touched his lips with it. That coal represented in itself the consuming of all the offerings and sacrifices of Israel. in their being offered to God. It represented all that was good in the sacrificial system. It represented the God-provided means of atonement. And when Isaiah later condemned the Israelite perversion of the sacrificial system (compare Isaiah 1:10), it was not this that he condemned. This represented the good side, the God provided side, of that system. He realised that he was covered by the shedding of blood, by the death of a thousand substitutes offered on his behalf, but all pointing ahead to the One great Substitute Who would be offered for the sins of many (Isaiah 53:5; Isaiah 53:12; Romans 5:25).
That the seraph flew at God's command is not stated but can be assumed, for in His presence none would dare to move except at His command, whether expressed or unexpressed. There He was all prevailing.
‘A live coal from the altar.' Its glowing ‘life' represented its immediacy in connection with the recent offerings and sacrifices. It had helped to consume the current sacrifices. Thus it represented present atonement. The thought is not of fire purging, but of the sacrificial significance applied, as the words of the seraph reveal. By it his sins would be ‘covered', atoned for. He could thus once more look upwards to God with hope.
‘He touched my mouth with it, and said, “Lo, this has touched your lips, and your iniquity is taken away, and your sin is purged.' It was his ‘lips', his mouth, that Isaiah had declared to be the proof of his utter sinfulness, and so it was his mouth that was symbolically cleansed. His unclean lips were now touched by the God-provided means of atonement. His iniquity was taken away, his sin was purged. Rightly used and approached the sacrifices were still effective for atonement to those who truly sought God, until One would come Who would Himself be the ultimate sacrifice for the sins of the world (Isaiah 53). Then all would need to look to Him.
‘Taken away -- purged.' ‘Iniquity' is the sin deep within that affects our very ‘hearts (our inward beings), and is an essential part of our sinning, staining us in God's presence. But now for Isaiah this was taken away, removed, got rid of. ‘Sin' is the actual outworking of iniquity in wrongful action, and that too was ‘purged, covered, atoned for'. There was now no barrier between Isaiah and God. The result was that from a position of complete self-despair he came to a place of being able to listen to the voice of the Lord God.
For us there is better than even this live coal, for we may see Jesus Who was the one sacrifice for sin for all time, and we may call on Him knowing that, if we admit to Him our sin and look to Him, the blood of Jesus Christ, God's Son, cleanses us from all sin (1 John 1:7).
‘And I heard the voice of the Lord, saying, “Whom shall I send, and who will go for us?” Then I said, “Here I am. Send me.”
The plural ‘us' reveals that God is talking to the seraphim. They were His support in the work of salvation. Or it may be a plural of majesty. We can compare it with the ‘us' spoken at creation (Genesis 1:26). But the question was really intended for Isaiah. It was the voice of the Sovereign Lord seeking for a messenger. Any one of the seraphim would have been delighted to be the messenger, but it is a sign of how Isaiah had been transformed by his experience that he steps into the conversation and offers himself to be the messenger. Filled with gratitude and awe he cries, “I am here, send me.”
We should recognise from this that any true experience of God will do the same. Once we have truly known God we cannot but speak of those things which we have seen and heard.
‘And he said, “Go, and tell this people, ‘Hear you indeed, but do not understand, and see you indeed, but do not perceive.' Make the heart of this people fat, and make their ears heavy, and shut their eyes, lest they see with their eyes, and hear with their ears, and understand with their heart, and turn again and be healed.' ”'
God does not want Isaiah to be deceived into thinking that his ministry will be gloriously successful. The message that he as messenger will have to bear will not be an easy one. He is called to go to a stubborn people, and most would remain stubborn to the end.
Some ministries are much harder than others, and outward success is not the only criterion of the genuineness of a man's calling. Some sow, and others reap (John 4:37). The words did not describe literally all he had to say (his whole prophecy indicates how wide ranging his message was), but they were the essence of what would be achieved. As he proclaimed God's truth and saw the people's negative reaction, (and that, God stressed, is what he must mainly expect), he would be driven to point out to them what was happening. They were hearing, but they were not accepting with understanding, they were outwardly seeing, but not inwardly perceiving. Thus the more they heard the more they would become hardened to his words because their hearts were closed. Yet let them but open their hearts and they would both see and hear.
But he knew that most would not. The result of his words would only be that their hearts would become fat (clogged up, inactive), their ears heavy, their eyes closed. They would refuse even more to see, they would refuse even more to hear, they would refuse even more to understand. Like Pharaoh they would harden their hearts, and become hardened, and all through God's activity in seeking to reach perverse hearts.
There is a slight sarcasm in the final phrases. By constantly preaching to them he will be finally ensuring that the vast majority do not respond and be healed. And the more he proclaims God's word the more certain it will be. Thus paradoxically by preaching to them he is making their turning to God theoretically less likely because they will have hardened themselves further. It is not that God does not want them to turn, He has no pleasure in the death of the wicked. It is rather that He sees their hearts, He knows what their response will be and how they will react. How by their hearing they will be even more hardened. How by their obstinacy they will destroy themselves. Thus He knows that His very act of seeking to help them will result in their condemnation. By pleading with them He will be hardening their hearts. And yet they must be given the opportunity.
But what if He had left them alone? Would they have turned? Of course not. Their hearts were so set that turning was not for them. It was only a theoretical possibility, not a practical one. They would simply become theoretically ‘less reachable'. Previously it was certain from God's viewpoint that most would not respond, after the preaching it will be even more certain. The hardening will have taken place. Even the theoretical possibility will have been removed. Then why preach to them? Firstly because it gave them every chance to exercise the theoretical possibility. Once they had heard His word they could blame no one but themselves. God's justice and fairness would be revealed. Up to that point they could have said, ‘if only we had known'. After it they had no excuse. And secondly because some few would respond as God worked in grace on their hearts. There would be ‘a holy seed' (Isaiah 6:13). God's purpose for the few would be carried through in the hardening of the many.
We can compare how when Jesus preached to the antagonistic among the Pharisees His words hardened them. Instead of responding they became more antagonistic, and so much so that He had to warn them that they were in danger of ‘blasphemy against the Holy Spirit', that hardening against the Spirit that guarantees that no response can be even theoretically possible. And He knew that this would happen, but He still gave them their opportunity. They would not come because they were not of His sheep, given to Him by the Father (John 10:26; John 10:29). Yet through His words some among the Pharisees did come. The hardening of the many had to be, for the sake of the few.
We have here specifically expressed the mystery of God's sovereignty and man's responsibility. Man is ever free to choose, but his freedom is limited by what he is. God is sovereign over all and in the end it is His purposes that will be worked out. And He knows what the consequences of what He does will be. And so, in a real sense, He is responsible for all. When He allowed Pharaoh's heart to be hardened by Pharaoh himself in the time of Moses, He knew that by His continued actions He was hardening Pharaoh's heart. When He arranged for a messenger to these people, He knew that He was bringing about the consequences described, that He was bringing about the sealing of the ears, the closing of the eyes, the hardening of the heart. And yet it was they who were responsible for their own response. It came because of what they were. No blame could be attached to God. Thus does He carry through His purposes.
‘Then I said, “Lord, how long?” '
We can understand Isaiah's misgivings. How long must he engage in this thankless task? What will be the limit? He is ready to obey but wishes for a limit to be put on what he has to do. But he has to learn that there is no limit. He must go on to the end. God has purposed judgment and he must go on until that judgment is fulfilled. There is no let up in the work of God.
‘And he answered,
“Until the cities be waste without inhabitant,
And houses without man,
And the land become utterly waste,
And Yahweh has removed men far away,
And the forsaken places be many in the midst of the land.
And if there be yet a tenth in it, it will again be eaten up.
As a terebinth and as an oak whose stump remains when they are felled,
So the holy seed is its stump.” '
Apart from a few details the whole of Isaiah's message is contained in these words. From the moment of his calling he was informed that one day first Israel, and then Judah and Jerusalem, would be invaded, would be taken over, and would be carried into exile. It was the inevitable consequence of the fact that they would not hear. The cities would be wasted. The houses emptied of occupation. The land would become a wilderness. The inhabitants would be removed far away, either by captivity or flight Few would remain. Only a ‘tenth' would be left. But would this be a new beginning? No. For even for them would come judgment, for the land would be ‘eaten up' again. And then finally after all the felling there would be a stump left. The holy seed would be the stump (Isaiah 4:3).
This then was God's purpose. Although He would yet spare and delay, the end was inevitable because of what men were. The whole would be whittled down to a tenth (a small proportion). But this tenth was not the Lord's, and they would refuse Him even that tenth. So that tenth would be whittled down even further. The land was doomed because the covenant which gave them the land was broken. Yet out of all of it would come a stump. And that stump was the holy seed that He continually promised, the final remnant. Only God could populate Heaven from a stump!
The terebinth and the oak were both symbols of Israel's sin (Isaiah 1:29; Hosea 4:13). Thus the thought includes the hewing down of idolatry out of which would spring the holy seed.
Note. While Assyria were the initial rod of God's anger (Isaiah 10:5), Isaiah was to learn later that this would not be just by Assyria. Thus when the Babylonians came on the horizon he knew in his heart, guided by God, that they also would contribute to Judah's downfall (Isaiah 39:5), and would later learn and recognise, again by God's inspiration, through whom initially deliverance would come, the house of Cyrus I of Persia (Isaiah 44:28 to Isaiah 45:1). Thus he knew the essence of what was coming, without the detail, and could give due warning. He was a prophet not a fortune teller. End of note.
