Yochanan 13:3-5

Yeshua, knowing that the Father had given all things into his hands, and that he came from God and was going to God, arose from supper, and laid aside his outer garments. He took a towel and wrapped a towel around his waist. Then he poured water into the basin, and began to wash the disciples’ feet and to wipe them with the towel that was wrapped around him.
