От Иоанна 13:9

Lord, not my feet only, but also my hands and my head--that is, "To be severed from Thee, Lord, is death to me: If that be the meaning of my speech, I tread upon it; and if to be washed of Thee have such significance, then not my feet only, but hands, head, and all, be washed!" This artless expression of clinging, life-and-death attachment to Jesus, and felt dependence upon Him for his whole spiritual well-being, compared with the similar saying in Joh 6:68-69 (see on Joh 6:68-69), furnishes such evidence of historic verity such as no thoroughly honest mind can resist.

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 (Joh 13:18-30). III. He instructs them in the great doctrine of his own death, and the great duty of brotherly love (Joh 13:31-35). IV. He foretels Peter's denying him (Joh 13:36-38).

13:9 wash my hands and head as well: Peter misunderstood Jesus (cp. 2:19-20; 3:3-4). Peter thought that to have more water was to have more of Jesus. Only when Peter received the Spirit did everything become clear (e.g., see Acts 2:14-36).
