John Trapp Complete Commentary
Isaiah 6:10
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 convert, and be healed.
Ver. 10. Make the heart of this people fat,] sc., By preaching to them the Word of God, which, because they regard not, it shall become unto them a savour of death, as sweet ointments kill beetles, as a shrill voice hurteth weak ears, as lime is kindled by cold water cast upon it. Of such a fat heart beware. Fat things are less sensible, and fat hearted people are noted by Aristotle for dull and stupid. There is not a greater mischief can befall a man on this side hell than to be given up to a dead and dedolent disposition, such as was that of those Eph 4:18 of the Jews in Christ's time, and ever since, and of many Papists, who continue blind in the midst of so much light, and will not renounce those errors whereof they are clearly convinced.
And make their ears heavy.] Preach them to hell. This is an accidental effect of the word preached, and proceedeth from men's corruptions. Zec 7:11 But as a hard heart, so a heavy ear is a singular judgment. Act 7:51 Antagoras, reciting his "Thebais," a book that he had made, among the Boeotians, and they little regarding him, he folded up his book, and said, Ye may well be called Boeotians, quia boum habetis aures, for ye have oxes' ears - playing upon the notation of their name. a
Lest they should see with their eyes, &c.] Or, That they may not see with their eyes, or hear, &c., but be as so many sots and stocks or statues, that have eyes and see not, &c., to their utter ruin and destruction. Neither is there any the least injustice in such a proceeding. An apprentice hath given him by his master a candle to light him to bed, which he abuseth to light him to game or drink. Hereupon his master taketh it from him, bloweth it out, and sendeth him darkling to bed, in the way whereto he breaketh his arms or his face by some fall: will any man blame the master, since the candle was his, and allowed for use? I think not. Think the like here.
And convert.] Which at times they would not, now they shall not; but having made a match with mischief, they shall henceforth have enough of it; they "love to have it so"; Jer 5:31 they "forsake their own mercies"; Jon 2:8 they are miserable by their own election.
And be healed,] i.e., Pardoned and purged. Atque hic pulchre exprimitur, saith one, ordo obtinendae salutis; and here is excellently set forth the order of obtaining salvation. For (1.) It is requisite that we have ears to hear, and eyes to see - not ears stopped, and eyes daubed up as these had; (2.) That what we hear and see, we understand with the heart - that is, that there be yielded thereunto both assent of the mind and consent of the will, this is faith; (3.) That we turn to the Lord by true repentance, and then we are sure of healing, which is by pardon of sin, and power against it.
