Luke 22:2-6

22:2 The chief priests and the experts in the law were trying to find some way to execute Jesus, for they were afraid of the people.

22:3 Then Satan entered Judas, the one called Iscariot, who was one of the twelve. 22:4 He went away and discussed with the chief priests and officers of the temple guard how he might betray Jesus, handing him over to them. 22:5 They were delighted and arranged to give him money. 22:6 So Judas agreed and began looking for an opportunity to betray Jesus when no crowd was present.
