Exodus 13:6-7 Ex. 13:6-7
6 Seven days thou shalt eat unleavened bread, and in the seventh day shall be a feast to the LORD. 7 Unleavened bread shall be eaten seven days; and there shall no leavened bread be seen with thee, neither shall there be leaven seen with thee in all thy quarters.
Mark 14:12-16 Mk. 14:12-16
12 And the first day of unleavened bread, when they killed the passover, his disciples said unto him, Where wilt thou that we go and prepare that thou mayest eat the passover? 13 And he sendeth forth two of his disciples, and saith unto them, Go ye into the city, and there shall meet you a man bearing a pitcher of water: follow him. 14 And wheresoever he shall go in, say ye to the goodman of the house, The Master saith, Where is the guestchamber, where I shall eat the passover with my disciples? 15 And he will shew you a large upper room furnished and prepared: there make ready for us. 16 And his disciples went forth, and came into the city, and found as he had said unto them: and they made ready the passover.
