John 13:4-15

got up from supper, took off His [outer] robe, and taking a [servant’s] towel, He tied it around His waist. Then He poured water into the basin and began washing the disciples’ feet and wiping them with the towel which was tied around His waist. When He came to Simon Peter, he said to Him, “Lord, are You going to wash my feet?” Jesus replied to him, “You do not realize now what I am doing, but you will [fully] understand it later.” Peter said to Him, “You will never wash my feet!” Jesus answered, “Unless I wash you, you have no part with Me [we can have nothing to do with each other].” Simon Peter said to Him, “Lord, [in that case, wash] not only my feet, but also my hands and my head!” Jesus said to him, “Anyone who has bathed needs only to wash his feet, and is completely clean. And you [My disciples] are clean, but not all of you.” For He knew who was going to betray Him; for that reason He said, “Not all of you are clean.” So when He had washed their feet and put on His [outer] robe and reclined at the table again, He said to them, “Do you understand what I have done for you? You call Me Teacher and Lord, and you are right in doing so, for that is who I am. So if I, the Lord and the Teacher, washed your feet, you ought to wash one another’s feet as well. For I gave you [this as] an example, so that you should do [in turn] as I did to you.
