Now before the festival of the Passover, Jesus knew that his hour had come to depart from this world and go to the Father. Having loved his own who were in the world, he loved them to the end. The devil had already put it into the heart of Judas son of Simon Iscariot to betray him. And during supper Jesus, knowing that the Father had given all things into his hands, and that he had come from God and was going to God, got up from the table, took off his outer robe, and tied a towel around himself. Then he poured water into a basin and began to wash the disciples’ feet and to wipe them with the towel that was tied around him. He came to Simon Peter, who said to him, ‘Lord, are you going to wash my feet?’ Jesus answered, ‘You do not know now what I am doing, but later you will understand.’ Peter said to him, ‘You will never wash my feet.’ Jesus answered, ‘Unless I wash you, you have no share with me.’ Simon Peter said to him, ‘Lord, not my feet only but also my hands and my head!’ Jesus said to him, ‘One who has bathed does not need to wash, except for the feet, but is entirely clean. And you are clean, though not all of you.’ For he knew who was to betray him; for this reason he said, ‘Not all of you are clean.’

After he had washed their feet, had put on his robe, and had returned to the table, he said to them, ‘Do you know what I have done to you? You call me Teacher and Lord—and you are right, for that is what I am. So if I, your Lord and Teacher, have washed your feet, you also ought to wash one another’s feet. For I have set you an example, that you also should do as I have done to you. Very truly, I tell you, servants are not greater than their master, nor are messengers greater than the one who sent them.

John 13.1-16

The Pharisees Question Jesus – James Tissot

Again they came to Jerusalem. As he was walking in the temple, the chief priests, the scribes, and the elders came to him and said, ‘By what authority are you doing these things? Who gave you this authority to do them?’ Jesus said to them, ‘I will ask you one question; answer me, and I will tell you by what authority I do these things. Did the baptism of John come from heaven, or was it of human origin? Answer me.’ They argued with one another, ‘If we say, “From heaven”, he will say, “Why then did you not believe him?” But shall we say, “Of human origin”?’—they were afraid of the crowd, for all regarded John as truly a prophet. So they answered Jesus, ‘We do not know.’ And Jesus said to them, ‘Neither will I tell you by what authority I am doing these things.’

Mark 11.27-33

Then they came to Jerusalem. And he entered the temple and began to drive out those who were selling and those who were buying in the temple, and he overturned the tables of the money-changers and the seats of those who sold doves; and he would not allow anyone to carry anything through the temple. He was teaching and saying, ‘Is it not written,
“My house shall be called a house of prayer for all the nations”?
But you have made it a den of robbers.’
And when the chief priests and the scribes heard it, they kept looking for a way to kill him; for they were afraid of him, because the whole crowd was spellbound by his teaching. And when evening came, Jesus and his disciples went out of the city.

Mark 11.15-19

Six days before the Passover Jesus came to Bethany, the home of Lazarus, whom he had raised from the dead. There they gave a dinner for him. Martha served, and Lazarus was one of those at the table with him. Mary took a pound of costly perfume made of pure nard, anointed Jesus’ feet, and wiped them with her hair. The house was filled with the fragrance of the perfume. But Judas Iscariot, one of his disciples (the one who was about to betray him), said, ‘Why was this perfume not sold for three hundred denarii and the money given to the poor?’ (He said this not because he cared about the poor, but because he was a thief; he kept the common purse and used to steal what was put into it.) Jesus said, ‘Leave her alone. She bought it so that she might keep it for the day of my burial. You always have the poor with you, but you do not always have me.’
