15 Seven days you shall eat unleavened bread; on the first day you shall remove leaven from your houses, for whoever eats leavened bread from the first day until the seventh day shall be cut off from Israel. 16 On the first day you shall hold a solemn assembly, and on the seventh day a solemn assembly; no work shall be done on those days; only what everyone must eat, that alone may be prepared by you. 17 You shall observe the festival of unleavened bread, for on this very day I brought your companies out of the land of Egypt: you shall observe this day throughout your generations as a perpetual ordinance. 18 In the first month, from the evening of the fourteenth day until the evening of the twenty-first day, you shall eat unleavened bread. 19 For seven days no leaven shall be found in your houses; for whoever eats what is leavened shall be cut off from the congregation of Israel, whether an alien or a native of the land. 20 You shall eat nothing leavened; in all your settlements you shall eat unleavened bread.
