John Calvin's Bible Commentary
Jeremiah 38:20
Here again Jeremiah strengthens Zedekiah, that he might not hesitate to make the trial, since God would yet give him pardon, so that at least his chastisement would be paternal and light He then promised to Zedekiah that he would be safe from all the insults about which he was anxious. They will not deliver thee, he says; as though he had said, “Leave this to God’s providence, resign thyself to God, and doubt not but that he will keep thee safe.” God, in his kindness, as I have said, allows the faithful to cast their cares into his bosom: but at the same time, if any disobey, when he confirms them, it is a sign of deliberate wickedness, and such perverseness extinguishes all the light of grace. Such was the stupidity of Zedekiah, that he did not accept of this second promise. He might indeed have confessed his fear, but he ought also to have received the remedy. The Prophet assured him that his life would be safe in God’s hand; what more could he have wished? But this was said to no purpose, because fear fully occupied his mind, so that there was no entrance for the promise. Now this ought to be carefully noticed; for there are none of us whom many cares do not disturb, and many fears do not perplex; but a place ought to be given to a remedy. God succors us when he sees us distressed by anxious thoughts; but if fear so prevails, that all the promises by which God raises us up avail nothing, it is a sign of hopeless unbelief.
It afterwards follows, Hear the voice of Jehovah, which I utter to you, that it may be well with thee, and that thy soul, may live The promise is again added, to lead Zedekiah to submit more willingly to God. For though we know that we cannot escape his power, it will yet be dreaded by us, except he favors us with the promises of grace. In this way, then, the Prophet endeavored to lead Zedekiah to render obedience to God: Hear, he says, the voice of Jehovah, that it may be well with thee He shewed that it was yet in the power of Zedekiah to provide for his own safety, if only he obeyed the word of God. And this passage teaches us, that the Prophet had not spoken thoughtlessly and in vain, but under the guidance and teaching of God’s Spirit For though it may not have been, that he had received a new command, he yet knew that it was God’s will, that he should confirm and reassert the previous oracles; for he did not falsely assume God’s name, when he bade Zedekiah to hear God’s voice which he had made known.
Now, though this discourse was especially directed to Zedekiah, we may yet conclude, that it is always for our good to embrace whatever God declares to us, though it may apparently be hard and unpleasant, as it was to Zedekiah; for it was by no means an agreeable thing to him to deliver up himself to his enemies, to be deprived of his regal power, to be drawn into exile, and from a king to become a slave; and yet nothing was better for him, in order to save his life, than to obey God. Though, then, the words of God contain what is contrary and grievous to our flesh, yet let us feel persuaded that God always speaks what is good for our salvation. It would then have been well for Zedekiah, had he obeyed the counsel of the Prophet; for he would have found in captivity that God would be propitious to him, and this would have been an invaluable comfort; and then he might have been brought back from exile, at least he would have preserved the city and the Temple: but by his obstinacy he betrayed the city to his enemies, and hence it was also that the Temple was burnt.
