Our Saviour having finished his public discourses, in which he "endured the contradiction of sinners, now applies himself to a private conversation with his friends, in which he designed the consolation of saints. Henceforward we have an account of what passed between him and his disciples, who were to be entrusted with the affairs of his household, when he was gone into a far country; the necessary instructions and comforts he furnished them with. His hour being at hand, he applies himself to set his house in order. In this chapter I. He washes his disciples feet (v. 1-17). II. He foretels who should betray him (v. 18-30). III. He instructs them in the great doctrine of his own death, and the great duty of brotherly love (v. 31-35). IV. He foretels Peters denying him (v. 36-38).
Verses 1-17 It has generally been taken for granted by commentators that Christs washing his disciples feet, and the discourse that followed it, were the same night in which he was betrayed, and at the same sitting wherein he ate the passover and instituted the Lords supper; but whether before the solemnity began, or after it was all over, or between the eating of the passover and the institution of the Lords supper, they are not agreed. This evangelist, making it his business to gather up those passages which the others had omitted, industriously omits those which the others had recorded, which occasions some difficulty in putting them together. If it was then, we suppose that Judas went out (v. 30) to get his men ready that were to apprehend the Lord Jesus in the garden. But Dr. Lightfoot is clearly of opinion that this was done and said, even all that is recorded to the end of ch. 14, not at the passover supper, for it is here said (v. 1) to be before the feast of the passover, but at the supper in Bethany, two days before the passover (of which we read Mt. 26:2-6 ), at which Mary the second time anointed Christs head with the remainder of her box of ointment. Or, it might be at some other supper the night before the passover, not as that was in the house of Simon the leper, but in his own lodgings, where he had none but his disciples about him, and could be more free with them.In these verses we have the story of Christs washing his disciples feet; it was an action of a singular nature; no miracle, unless we call it a miracle of humility. Mary had just anointed his head; now, lest his acceptance of this should look like taking state, he presently balances it with this act of abasement. But why would Christ do this? If the disciples feet needed washing, they could wash them themselves; a wise man will not do a thing that looks odd and unusual, but for very good causes and considerations. We are sure that it was not in a humour or a frolic that this was done; no, the transaction was very solemn, and carried on with a great deal of seriousness; and four reasons are here intimated why Christ did this:1. That he might testify his love to his disciples, v. 1, v. 2. That he might give an instance of his own voluntary humility and condescension, v. 3-5. That he might signify to them spiritual washing, which is referred to in his discourse with Peter, v. 6-11. That he might set them an example, v. 12-17. And the opening of these four reasons will take in the exposition of the whole story.I. Christ washed his disciples feet that he might give a proof of that great love wherewith he loved them; loved them to the end, v. 1, v. 2.1. It is here laid down as an undoubted truth that our Lord Jesus, having loved his own that were in the world, loved them to the end, v. 1
