John 13:2-5
ESV
2 During supper, when the devil had already put it into the heart of Judas
Iscariot, Simon’s son, to betray him, 3 Jesus, knowing that the Father had
given all things into his hands, and that he had come from God and was
going back to God, 4 rose from supper. He laid aside his outer garments,
and taking a towel, tied it around his waist. 5 Then he poured water into a
basin and began to wash the disciples feet and to wipe them with the towel
that was wrapped around him.
