John 13:4

13:3 Jesus, knowing that the Father had given all things into His hands, and that He had come from God and was going to God,

13:4 rose from supper and laid aside His garments, took a towel and girded Himself.

13:5 After that, He poured water into a basin and began to wash the disciples' feet, and to wipe them with the towel with which He was girded.
