John 13:12-20 - The Meaning Of Footwashing
12 Then when He washed their feet, and took His garments, and sat down again, He said to them, Do you understand what I have done to you? 13 You call me Master and Lord, and you speak beautifully; for I am. 14 If then I, your Lord and Master, washed your feet, you ought also to wash the feet of one another. 15 For I have given unto you an example, that you may also do as I have done to you.
16 Truly, truly, I say unto you, The servant is not greater than his lord; nor the apostle greater than him that sent him. 17 If you know these things, happy are ye if you may do them. 18 I do not speak concerning you all: I know whom I have chosen: but that the Scripture may be fulfilled, He that eateth bread with me has lifted up his heel against me.
19 Now I tell you before it takes place, in order that you may believe, when it may be done, that I am He. 20 Truly, truly, I say unto you, The one receiving the one whom I may send, receiveth me; and the one receiving me, receives Him that sent me.
