“When the disciples entered the upper room, Judas pushed his way next to Christ on the left side; John was on the right. If there was a highest place, Judas was determined to have it. Another cause of conflict had arisen. It was customary for a servant to wash the feet of the guests. On this occasion the pitcher, the basin, and the towel were in place and ready, but no servant was present, and it was the disciples’ duty to perform the task. But each determined not to act the part of a servant. All of them put on the appearance of unconcern. By their silence they refused to humble themselves.”
