Thematic Bible: Washing of, as an example, by jesus

he rises from supper, and lays aside his garments, and taking a towel, he wound it about himself. Then he poureth water into a bason, and began to wash the disciples' feet, and to wipe them with the towel with which he was begirt. Then cometh he to Simon Peter: and he saith to him, Lord, dost thou wash my feet? read more.
Jesus answered and said to him, What I am doing thou knowest not now; but thou shalt know hereafter. Peter saith to him, Thou shalt never wash my feet: no, never. Jesus answered him, Except I wash thee, thou hast no part with me. Simon Peter saith to him, Lord, not my feet only, but also my hands and my head. Jesus saith to him, He that is washed hath need only to wash his feet, for he is entirely clean: and ye are clean, but not all. (For he knew who would betray him; therefore he said, Ye are not all clean.) When therefore he had washed their feet, and taken his garments, and sat down again, he said unto them, Know ye what I have done unto you? Ye call me Master, and Lord: and ye speak truly; for such I am. If therefore I have washed your feet, though the Lord and the Master; ye also ought to wash one another's feet.
