15 Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven 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 And in the first day there shall be a holy convocation, and in the seventh day there shall be a holy convocation to you; no manner of work shall be done in them, except that which every person must eat, that only may be done of you.
17 And ye 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 ye observe this day for your ages by an ordinance forever.
18 In the first month, on the fourteenth day of the month in the evening, ye shall eat unleavened bread until the twenty-first day of the month in the evening.
19 For seven days there shall be no leaven found in your houses; for whoever eats that which is leavened, that soul shall be cut off from the congregation of Israel, whether he is a stranger or born in the land.
20 Ye shall eat nothing leavened; in all your habitations ye shall eat unleavened bread.
21 Then Moses called for all the elders of Israel and said unto them, Draw out and take lambs according to your families and sacrifice the passover.
