John 13:3-5
13:3 Because Jesus knew that the Father had handed all things over to him, and that he had come from God and was going back to God,
13:4 he got up from the meal, removed his outer clothes, took a towel and tied it around himself.
13:5 He poured water into the washbasin and began to wash the disciples’ feet and to dry them with the towel he had wrapped around himself.
