Exodus 12:15-17 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.
