The Feast of Unleavened Bread, called the Passover, was near.
The chief priests and the teachers of the law were looking for a way to get rid of Jesus. They were afraid of the people.
Then Satan entered Judas, who was called Iscariot. Judas was one of the Twelve.
He went to the chief priests and the officers of the temple guard. He talked with them about how he could hand Jesus over to them.
They were delighted and agreed to give him money.
Judas accepted their offer. He watched for the right time to hand Jesus over to them. He wanted to do it when no crowd was around.
