Luke 22:2-4

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.
