Conspiracy at Caiaphas’s palace
Matthew 26:3-5

3 Then assembled together the chief priests, and the scribes, and the elders of the people, unto the palace of the high priest, who was called Caiaphas,
4 And consulted that they might take Jesus by subtilty, and kill him.
5 But they said, Not on the feast day, lest there be an uproar among the people.
