Lord, dost thou wash my feet? This speech expresses strong dislike of the action as foolish and unsuitable; for by asking what Christ is doing, he puts out his hand, as it were, to push him back. The modesty would be worthy of commendation, were it not that obedience is of greater value in the sight of God than any kind of honor or service, or rather, if this were not the true and only rule of humility, to yield ourselves in obedience to God, and to have all our senses regulated by his good pleasure, so that every thing which he declares to be agreeable to Him shall also be approved by us, without any scruple. We ought, therefore, above all, to observe this rule of serving God, that we shall be always ready to acquiesce, without delay, as soon as he issues any command.

Dost thou wash my feet? - Every word here is emphatic. Dost thou - the Son of God, the Messiah - perform the humble office of a servant - toward me, a sinner? This was an expression of Peter's humility, of his reverence for Jesus, and also a refusal to allow him to do it. It is possible, though not certain from the text, that he came to Simon Peter first.

Lord, dost Thou wash My feet? - Every word here is exceedingly emphatic. Peter had often seen the great humility of his Lord, but never saw his condescension so particularly marked as in this instance.

Then cometh he to Simon Peter,.... After having washed the feet of some of the disciples, as is thought by some interpreters, and particularly the feet of Judas, without any repulse; though others are of opinion that he began with Peter, who modestly, and out of reverence to him, refuses to be washed by him:
and Peter saith unto him, Lord, dost thou wash my feet! he speaks as one surprised and astonished that Christ should offer to do any such thing to him; that he, who was the Son of the living God, should wash the feet of such a sinful man as he was; that those hands, with which he had wrought such miracles, as the opening the eyes of the blind, cleansing lepers, and raising the dead, should be employed in washing his defiled feet, the meaner and inferior parts of his body; this he thought was greatly below his dignity and character, and too much to be done by him to such a worthless creature as he was.

Peter saith . . . Lord, dost thou wash my feet?--Our language cannot bring out the intensely vivid contrast between the "Thou" and the "my," which, by bringing them together, the original expresses, for it is not good English to say, "Lord, Thou my feet dost wash?" But every word of this question is emphatic. Thus far, and in the question itself, there was nothing but the most profound and beautiful astonishment at a condescension to him quite incomprehensible. Accordingly, though there can be no doubt that already Peter's heart rebelled against it as a thing not to be tolerated, Jesus ministers no rebuke as yet, but only bids him wait a little, and he should understand it all.

Lord, dost thou wash my feet? The language of Peter is that of confusion, of astonishment and of remonstrance. The emphasis is on the word thou.
