Exodus 12:15-17

New Revised Standard Version Catholic Edition

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.
