John 13:12-20 - The Meaning Of Footwashing
12 When, therefore, he washed their feet, and took his garments, having reclined (at meat) again, he said to them, 'Do ye know what I have done to you? 13 ye call me, The Teacher and The Lord, and ye say well, for I am; 14 if then I did wash your feet -- the Lord and the Teacher -- ye also ought to wash one another's feet. 15 'For an example I gave to you, that, according as I did to you, ye also may do;
16 verily, verily, I say to you, a servant is not greater than his lord, nor an apostle greater than he who sent him; 17 if these things ye have known, happy are ye, if ye may do them; 18 not concerning you all do I speak; I have known whom I chose for myself; but that the Writing may be fulfilled: He who is eating the bread with me, did lift up against me his heel.
19 From this time I tell you, before its coming to pass, that, when it may come to pass, ye may believe that I am he; 20 verily, verily, I say to you, he who is receiving whomsoever I may send, doth receive me; and he who is receiving me, doth receive Him who sent me.'
