John 13:11-21 WNT

11 For He knew who was betraying Him, and that was why He said, "You are not all of you clean."
12 So after He had washed their feet, put on His garments again, and returned to the table, He said to them, "Do you understand what I have done to you?
13 You call me `The Rabbi' and `The Master,' and rightly so, for such I am.
14 If I then, your Master and Rabbi, have washed your feet, it is also your duty to wash one another's feet.
15 For I have set you an example in order that you may do what I have done to you.
16 In most solemn truth I tell you that a servant is not superior to his master, nor is a messenger superior to him who sent him.
17 If you know all this, blessed are you if you act accordingly.
18 I am not speaking of all of you. I know whom I have chosen, but things are as they are in order that the Scripture may be fulfilled, which says, `He who eats my bread has lifted up his heel against me.'
19 From this time forward I tell you things before they happen, in order that when they do happen you may believe that I am He.
20 In most solemn truth I tell you that he who receives whoever I send receives me, and that he who receives me receives Him who sent me."
21 After speaking thus Jesus was troubled in spirit and said with deep earnestness, "In most solemn truth I tell you that one of you will betray me."
