15 Seven days shall you eat unleavened bread; even the first day you shall put away yeast out of your houses, for whoever eats leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.
16 In the first day there shall be to you a holy convocation, and in the seventh day a holy convocation; no manner of work shall be done in them, except that which every man must eat, that only may be done by you.
17 You shall observe the feast of unleavened bread; for in this same day have I brought your hosts out of the land of Egypt: therefore shall you observe this day throughout your generations by an ordinance forever.
18 In the first month, on the fourteenth day of the month at evening, you shall eat unleavened bread, until the twenty first day of the month at evening.
19 Seven days shall there be no yeast found in your houses, for whoever eats that which is leavened, that soul shall be cut off from the congregation of Israel, whether he be a foreigner, or one who is born in the land.
20 You shall eat nothing leavened. In all your habitations you shall eat unleavened bread.'"
