NO LEAVEN SHALL BE IN OUR HOUSES OR EATEN FOR 7 DAYS

Exodus 12:15 Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whosoever eats leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.

Exodus 12:19 Seven days shall there be no leaven found in your houses: for whosoever eats 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.

Exodus 12:20 Ye shall eat nothing leavened; in all your habitations shall ye eat unleavened bread.
