Luke 22:1-6 CSB
The Festival of Unleavened Bread, which is called Passover, was approaching. The chief priests and the scribes were looking for a way to put him to death, because they were afraid of the people.
Then Satan entered Judas, called Iscariot, who was numbered among the Twelve. He went away and discussed with the chief priests and temple police how he could hand him over to them. They were glad and agreed to give him silver. So he accepted the offer and started looking for a good opportunity to betray him to them when the crowd was not present.
