John 13:2

And when supper was done. By this we must not understand, that the supper was over; for we afterwards find that Jesus again sat down, and gave bread to the traitor. But these words only mean, that all had partook of refreshment, and might be therefore said to have supped. (St. Augustine, tract. 55. in Joan.) — He knew that he went out from God, and would return to God; but at the same time, he did not leave God, when he went out from him, nor us, when he returns to him. (St. Augustine, as above.) — And though he went out from God, and returns to him, yet here he condescends to perform the office, not of the Lord God of the universe, but of a man and a slave; (St. Augustine) and this, says St. Chrysostom, (hom. lxix. in Joan.) that he might tread all pride under foot: doing every thing himself on this occasion, to teach us with what eagerness we ought to perform the duties of humility.

(3.) He rose from supper to do it. Though we translate it (v. 2) supper being ended, it might be better read, there being a supper made, or he being at supper, for he sat down again (v. 12), and we find him dipping a sop (v. 26), so that he did it in the midst of his meal, and thereby taught us, [1.] Not to reckon it a disturbance, nor any just cause of uneasiness, to be called from our meal to do God or our brother any real service, esteeming the discharge of our duty more than our necessary food, ch. 4 34. Christ would not leave his preaching to oblige his nearest relations (Mark 3 33), but would leave his supper to show his love to his disciples. [2.] Not to be over nice about our meat. It would have turned many a squeamish stomach to wash dirty feet at supper-time; but Christ did it, not that we might learn to be rude and slovenly (cleanliness and godliness will do well together), but to teach us not to be curious, not to indulge, but mortify, the delicacy of the appetite, giving good manners their due place, and no more.

Verses 1-17 Our Lord Jesus has a people in the world that are his own; he has purchased them, and paid dear for them, and he has set them apart for himself; they devote themselves to him as a peculiar people. Those whom Christ loves, he loves to the end. Nothing can separate a true believer from the love of Christ. We know not when our hour will come, therefore what we have to do in constant preparation for it, ought never to be undone. What way of access the devil has to men's hearts we cannot tell. But some sins are so exceedingly sinful, and there is so little temptation to them from the world and the flesh, that it is plain they are directly from Satan. Jesus washed his disciples' feet, that he might teach us to think nothing below us, wherein we may promote God's glory, and the good of our brethren. We must address ourselves to duty, and must lay aside every thing that would hinder us in what we have to do. Christ washed his disciples' feet, that he might signify to them the value of spiritual washing, and the cleansing of the soul from the pollutions of sin. Our Lord Jesus does many things of which even his own disciples do not for the present know the meaning, but they shall know afterward. We see in the end what was the kindness from events which seemed most cross. And it is not humility, but unbelief, to put away the offers of the gospel, as if too rich to be made to us, or too good news to be true. All those, and those only, who are spiritually washed by Christ, have a part in Christ. All whom Christ owns and saves, he justifies and sanctifies. Peter more than submits; he begs to be washed by Christ. How earnest he is for the purifying grace of the Lord Jesus, and the full effect of it, even upon his hands and head! Those who truly desire to be sanctified,…
