It was just before the Passover Feast. Jesus knew that the time had come for him to leave this world and go to the Father. Having loved his own who were in the world, he now showed them the full extent of his love.
The evening meal was being served, and the devil had already prompted Judas Iscariot, son of Simon, to betray Jesus. Jesus knew that the Father had put all things under his power, and that he had come from God and was returning to god; so he got up from the meal, took off his outer clothing, and wrapped a towel around his waist. 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.
He came to Simon Peter, who said to him, "Lord, are you going to wash my feet?" Jesus replied, "You do not realize now what I am doing, but later you will understand." "No," said Peter, "you shall never wash my feet." Jesus answered, "Unless I wash you, you have no part in me." "Then, Lord," Simon Peter replied, "not just my feet but my hands and my head as well!"
Jesus answered, "A person who has had a bath needs only to wash his feet; his whole body is clean. And you are clean, though not every one of you." For he knew who was going to betray him, and that was why he said not every one was clean. When he finished washing their feet, he put on his clothes and returned to his place. "do you understand what I have done for you?" he asked them.
"You call me 'Teacher'  and 'Lord,' and rightly so, for that is what I am. Now that I, your Lord and Teacher, have washed your feet, you also should wash one another's feet. I have set you an example that you should do as I have done for you. I tell you the truth, no servant is greater than his master, nor is a messenger greater than the one who sent him. Now that you know these things, you will be blessed if you do them.
John 13: 1-17

When the hour came, Jesus and his apostles reclined at the table. And he said to them, "I have eagerly desired to eat this Passover with you before I suffer. For I tell you, I will not eat it again until it finds fulfillment in the kingdom of God."
After taking the cup, he gave thanks and said, "Take this and divide it among you. for I tell you I will not drink again of the fruit of the vine until the kingdom of God comes."
And he took bread, gave thanks and broke it, and gave it to them saying, "This is my body given for you; do this in remembrance of me."
In the same way, after the supper he took the cup, saying, "This cup is the new covenant in my blood, which is poured out for you. But the hand of him who is going to betray me is with mine on the table. The Son of Man will go as it has been decreed, but woe to that man who betrays him."
Luke 22: 14-22
