Mark 14:1-2
1 Two days before the Passover and the Feast of Unleavened Bread, the chief priests and the experts in the law were trying to find a way to arrest Jesus by stealth and kill him. 2 For they said, "Not during the feast, so there won't be a riot among the people."
Luke 22:1-2
1 Now the Feast of Unleavened Bread, which is called the Passover, was approaching. 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.
