Seven days there shall not be found any leaven in your houses: he that shall eat leavened bread, his soul shall perish out of the assembly of Israel, whether he be a stranger or born in the land.
Seven days shall you eat unleavened bread. In the first day there shall be no leaven in your houses: whosoever shall eat any thing leavened, from the first day until the seventh day, that soul shall perish out of Israel.
No leaven shall be seen in all thy coasts for seven days: neither shall any of the flesh of that which was sacrificed the first day in the evening remain until morning.
