Exodus 12:14–20

¹⁴‘And this day hath become to you a memorial, and ye have kept it a feast to Jehovah to your generations;—a statute age-during; ye keep it a feast. ¹⁵Seven days ye eat unleavened things; only—in the first day ye cause leaven to cease out of your houses; for any one eating anything fermented from the first day till the seventh day, even that person hath been cut off from Israel.

¹⁶‘And in the first day is a holy convocation, and in the seventh day ye have a holy convocation; any work is not done in them, only that which is eaten by any person—it alone is done by you, ¹⁷and ye have observed the unleavened things, for in this self-same day I have brought out your hosts from the land of Egypt, and ye have observed this day to your generations—a statute age-during.

¹⁸‘In the first month, in the fourteenth day of the month, in the evening, ye do eat unleavened things until the one and twentieth day of the month, at evening; ¹⁹seven days leaven is not found in your houses, for any one eating anything fermented—that person hath been cut off from the company of Israel, among the sojourners or among the natives of the land; ²⁰anything fermented ye do not eat, in all your dwellings ye do eat unleavened things.’
