John 13:2-5

Before their evening meal had begun, the accuser had already deeply embedded betrayal into the heart of Judas Iscariot, the son of Simon. Now Jesus was fully aware that the Father had placed all things under his control, for he had come from God and was about to go back to be with him. So he got up from the meal and took off his outer robe, and took a towel and wrapped it around his waist. Then he poured water into a basin and began to wash the disciples’ dirty feet and dry them with his towel.
