Yochanan (Jhn) 13:3-5

Yeshua was aware that the Father had put everything in his power, and that he had come from God and was returning to God. So he rose from the table, removed his outer garments and wrapped a towel around his waist. Then he poured some water into a basin and began to wash the feet of the talmidim and wipe them off with the towel wrapped around him.
