Exodus 12:20
19. Seven days shall there be no leaven found in your houses: for whosoever eateth that which is leavened, even that soul shall be cut off from the congregation of Israel, whether he be a stranger, or born in the land.20. Ye shall eat nothing leavened; in all your habitations shall ye eat unleavened bread.21. Then Moses called for all the elders of Israel, and said unto them, Draw out and take you a lamb according to your families, and kill the passover.
