And on the first day of unleavened bread, when they sacrificed the passover, his disciples said unto him, Where wilt thou that we go and make ready that thou mayest eat the passover? The first day of unleavened bread would begin on the evening of the Thursday (the 14th day of the month Nisan).
Where wilt thou that we prepare? They do not inquire in what city or town. The Passover could not be sacrificed anywhere but in Jerusalem. The question was in what house it was to be prepared.
