For Jesus knew who would betray him. That is what he meant when he said, "Not all of you are clean."
After washing their feet, he put on his robe again and sat down and asked, "Do you understand what I was doing? 13You call me 'Teacher' and 'Lord,' and you are right, because it is true. 14And since I, the Lord and Teacher, have washed your feet, you ought to wash each other's feet. 15I have given you an example to follow. Do as I have done to you. 16How true it is that a servant is not greater than the master. Nor are messengers more important than the one who sends them. 17You know these things -- now do them! That is the path of blessing."
18"I am not saying these things to all of you; I know so well each one of you I chose. The Scriptures declare, 'The one who shares my food has turned against me,' a and this will soon come true. 19I tell you this now, so that when it happens you will believe I am the Messiah. 20Truly, anyone who welcomes my messenger is welcoming me, and anyone who welcomes me is welcoming the Father who sent me."21
Now Jesus was in great anguish of spirit, and he exclaimed, "The truth is, one of you will betray me!"
