4But before he left us, he wanted to show us how we should love each other. So he got up from where he was eating. He took off his outer cloak and wrapped a long towel around his waist, as a slave would do.
5Then he poured some water in a basin. He began to wash our feet, and then dry them with the towel that he had wrapped around himself.
6When he came to Simon Peter, Peter said to him, “Lord, it is not right for you RHQ to humble yourself by washing my feet!”
7Jesus replied to him, “Now you do not understand the meaning of what I am doing, but you will understand later.”
8Peter said, “I will never, ever, allow you to wash my feet!” Jesus replied to him, “If I do not wash you, you cannot continue ◄to be my disciple/to belong to me►.”
9So Simon Peter said to him, “Lord, in that case, do not wash only my feet. Wash my hands and my head, too!”
10Then, to show him that after God had cleansed people from being guilty for sin, they needed only for God to forgive their daily sins MET, Jesus said to him, “Those who have recently bathed need only to have their feet washed, because they get dirty very quickly on the dusty roads. The rest of their bodies are clean. Similarly, I have made you disciples free/clean from the guilt of your sins, although not all of you are free from guilt.”
11He knew which one of us was going to betray him. That is the reason he said, “Not all of you are free from guilt.”
12After he finished washing our feet, he put his cloak back on. Then he sat down and said to us, “Do you understand what I have done for you?
13You show that you respect me by calling me ‘Teacher’ and ‘Lord’. You are right to say that, because I am your teacher and your Lord.
14But if I, who am your teacher and your Lord, have washed your feet, you ought to serve each other by doing things like washing each other's feet.
