There was also a dispute among them of who would be the greatest.
There was also a dispute among them of who would be the greatest. After supper, Jesus arose and laid aside his garments. He took a towel and girded himself and began to wash and to wipe his disciple's feet. At first Peter refused to have this done to him but later he consented. After this, Jesus sat down and said that he had given them an example. Just as he had done, they should likewise wash one another's feet. Whoever would be the greatest among them, must become the least. He added moreover that he was not speaking about everyone for he knew whom he had chosen. When he had said these things, he was troubled in the spirit and said that one of them would betray him. Therefore his disciples looked at each other and were uncertain of whom he referred to. Peter beckoned to the beloved disciple that he should ask who it was. Jesus answered that it was the one to whom he gave the sop after dipping it. He gave it to Judas and told him to quickly do what he had to do. When Judas had received the sop, he went out immediately and it was night. (JHN 13:2-38 LUK 22:24-30)
