Matthew 26v3-5

Heavenly father
give us grace today to avoid  doing anything which we know to be wrong, and to avoid doing anything by deception

3 Then the chief priests, the scribes, and the elders of the people 
were gathered together in the court of the high priest, who was called Caiaphas. 
4 They took counsel together that they might take Jesus by deceit and kill him. 
5 But they said, “Not during the feast, lest a riot occur among the people.”
