John 13:2-5, 12-14

The evening meal was in progress, and the devil had already prompted Judas, the son of Simon Iscariot, to betray Jesus. Jesus knew that the Father had put all things under his power, and that he had come from God and was returning to God; so he got up from the meal, took off his outer clothing, and wrapped a towel around his waist. After that, he poured water into a basin and began to wash his disciples’ feet, drying them with the towel that was wrapped around him.

When he had finished washing their feet, he put on his clothes and returned to his place. “Do you understand what I have done for you?” he asked them. “You call me ‘Teacher’ and ‘Lord,’ and rightly so, for that is what I am. Now that I, your Lord and Teacher, have washed your feet, you also should wash one another’s feet.
