And the passover and the unleavened food were after two days, and the chief priests and the scribes were seeking how, by guile, having taken hold of him, they might kill him;

And the first day of the unleavened food, when they were killing the passover, his disciples say to him, 'Where wilt thou, that, having gone, we may prepare, that thou mayest eat the passover?'
