Exodus 12:15-20 Seven days you shall eat unleavened bread, and from the first day you shall utterly remove leaven from your houses: whoever shall eat leaven, that soul shall be utterly destroyed from Israel, from the first day until the seventh day.

CAB⁽ⁱ⁾ ¹⁵ Seven days you shall eat unleavened bread, and from the first day you shall utterly remove leaven from your houses: whoever shall eat leaven, that soul shall be utterly destroyed from Israel, from the first day until the seventh day. ¹⁶ And the first day shall be called holy, and the seventh day shall be a holy convocation to you. You shall do no servile work on them, only as many things as is necessary shall be done by every soul, this only shall be done by you. ¹⁷ And you shall keep this commandment, for on this day will I bring out your force out of the land of Egypt; and you shall make this day a perpetual ordinance for you throughout your generations. ¹⁸ Beginning the fourteenth day of the first month, you shall eat unleavened bread from evening, till the twenty-first day of the month, till evening. ¹⁹ Seven days leaven shall not be found in your houses; whosoever shall eat anything leavened, that soul shall be cut off from the congregation of Israel, both among the occupiers of the land and the original inhabitants. ²⁰ You shall eat nothing leavened, but in every habitation of yours you shall eat unleavened bread.
