Exodus 12:14-16

New Revised Standard Version, Anglicised

¹⁴ This day shall be a day of remembrance for you. You shall celebrate it as a festival to the Lord; throughout your generations you shall observe it as a perpetual ordinance. 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.
