John 13:2-5

²During supper, the devil having already put into the heart of Judas Iscariot, the son of Simon, to betray Him, ³Jesus, knowing that the Father had given all things into His hands, and that He had come forth from God and was going back to God, ⁴got up from supper, and laid aside His garments; and taking a towel, He girded Himself. ⁵Then He poured water into the basin, and began to wash the disciples’ feet and to wipe them with the towel with which He was girded.
