John 13:3-5 NIV

[3] Jesus knew that the Father had put all things under his power, and that he had come from God and was returning to God; [4] so he got up from the meal, took off his outer clothing, and wrapped a towel around his waist. [5] After that, he poured water into a basin and began to wash his disciples’ feet, drying them with the towel that was wrapped around him.
