Before the festival of the Passover, Jesus, knowing that his hour had come to pass from this world to the Father, having loved those who were his in the world, loved them to the end.
They were at supper, and the devil had already put it into the mind of Judas Iscariot son of Simon, to betray him. Jesus knew that the Father had put everything into his hands, and that he had come from God and was returning to God, and he got up from table, removed his outer garments and, taking a towel, wrapped it round his waist; he then poured water into a basin and began to wash the disciples’ feet and to wipe them with the towel he was wearing. He came to Simon Peter, who said to him, ‘Lord, are you going to wash my feet?’
Jesus answered, ‘At the moment you do not know what I am doing, but later you will understand.’
‘Never!’ said Peter. ‘You shall never wash my feet.’
Jesus replied, ‘If I do not wash you, you can have no share with me.’ Simon Peter said,
‘Well then, Lord, not only my feet, but my hands and my head as well!’
Jesus said, ‘No one who has had a bath needs washing, such a person is clean all over. You too are clean, though not all of you are.’ He knew who was going to betray him, and that was why he said, ‘though not all of you are’.
When he had washed their feet and put on his outer garments again he went back to the table. ‘Do you understand’, he said, ‘what I have done to you? You call me Master and Lord, and rightly; so I am’.

Now has the Son of man been glorified, and in him God has been glorified. If God has been glorified in him, God will in turn glorify him in himself, and will glorify him very soon.
Little children, I shall be with you only a little longer. You will look for me, and, as I told the Jews, where I am going, you cannot come. I give you a new commandment: love one another; you must love one another just as I have loved you. It is by your love for one another, that everyone will recognise you as my disciples.
