Who did no sin This belongs to the present subject; for, if any one boasts of his own innocence, he must know that Christ did not suffer as a malefactor. He, at the same time, shews how far we come short of what Christ was, when he says, that there was no guile found in his mouth; for he who offends not by his tongue, says James, is a perfect man. (James 3:2.) He then declares that there was in Christ the highest perfection of innocency, such as no one of us can dare claim for himself. It hence appears more fully how unjustly he suffered beyond all others. There is, therefore, no reason why any one of us should refuse to suffer after his example, since no one is so conscious of having acted rightly, as not to know that he is imperfect.

Who did no sin - Who was in all respects perfectly holy. There is an allusion here to Isaiah 53:9; and the sense is, that he was entirely innocent, and that he suffered without having committed any crime. In this connection the meaning is, that we are to be careful that, if we suffer, it should be without committing any crime. We should so live, as the Saviour did, as not to deserve to be punished, and thus only shall we entirely follow his example. It is as much our duty to live so as not to deserve the reproaches of others, as it is to bear them with patience when we are called to suffer them. The first thing in regard to hard treatment from others, is so to live that there shall be no just occasion for it; the next is, if reproaches come upon us when we have not deserved them, to bear them as the Saviour did. If he suffered unjustly, we should esteem it to be no strange thing that we should; if he bore the injuries done him with meekness, we should learn that it is possible for us to do it also; and should learn also that we have not the spirit of his religion unless we actually do it. On the expression used here, compare the Isaiah 53:9 note; Hebrews 7:26 note.
Neither was guile found in his mouth - There was no deceit, hypocrisy, or insincerity. He was in all respects what he professed to be, and he imposed on no one by any false and unfounded claim. All this has reference to the time when the Saviour was put to death; and the sense is, that though he was condemned as an impostor, yet that the charge was wholly unfounded. As in his whole life before he was perfectly sincere, so he was eminently on that solemn occasion.

Who did no sin - He suffered, but not on account of any evil he had either done or said. In deed and word he was immaculate, and yet he was exposed to suffering; expect the same, and when it comes bear it in the same spirit. It is very likely that the apostle mentions guile, because those who do wrong generally strive to screen themselves by prevarication and lies. These words appear to be a quotation from Isaiah 53:9.

Who did no sin,.... He was in the likeness of sinful flesh; he looked like a sinful man, being born of a sinful woman, and keeping company with sinful men, being himself a man of sorrows, greatly afflicted, and at last put to death. He was traduced as a sinner by his enemies, and had all the sins of his people on him, which he bore, and made satisfaction for, and were the reason of his sufferings; but he had no sin in his nature, nor did he commit any in his life:
neither was guile found in his mouth; though it was diligently sought for, by the Scribes and Pharisees; there was no deceit in his lips, no falsehood in his doctrine, any more than there was immorality in his conversation; he was an Israelite indeed on all accounts, and in the fullest sense of that phrase; reference is had to Isaiah 53:9 and this is observed, partly to show that Christ suffered not for himself, or for any sins of his own, but for the sins of others, for which he was very fit, since he had none of his own; and partly as an argument for patience in suffering; for since Christ suffered, who had no sin, nor did any, nor could any be found in him, charged upon him, and proved against him; and which sufferings of his he bore with patience; then how much must it become sinful men to bear their sufferings patiently, though they may not be criminal with respect to the things for which they suffer, but yet are so in other things, whereas Christ was not criminal, nor blameworthy in anything?

Illustrating Christ's well-doing (1-Peter 2:20) though suffering.
did--Greek aorist. "Never in a single instance did" [ALFORD]. Quoted from Isaiah 53:9, end, Septuagint.
neither--nor yet: not even [ALFORD]. Sinlessness as to the mouth is a mark of perfection. Guile is a common fault of servants. "If any boast of his innocency, Christ surely did not suffer as an evildoer" [CALVIN], yet He took it patiently (1-Peter 2:20). On Christ's sinlessness, compare 2-Corinthians 5:21; Hebrews 7:26.

In all these instances the example of Christ is peculiarly adapted to the state of servants, who easily slide either into sin or guile, reviling their fellowservants, or threatening them, the natural result of anger without power. He committed himself to him that judgeth righteously - The only solid ground of patience in affliction. Isaiah 53:4, Isaiah 53:6-7, Isaiah 53:9.
