"Now my soul is troubled, and what shall I say? 'Father, deliver me from this hour'? But for this [reason] I have come to this hour!

So Jesus said to Peter, "Put the sword into [its] sheath! The cup that the Father has given me--shall I not drink it?"

Then those shouted, "Away [with him]! Away [with him]! Crucify him!" Pilate said to them, "Shall I crucify your king?" The chief priests replied, "We do not have a king except Caesar!"
