Exodus 12:15-19 Seven days ye shall eat unleavened bread, and from the first day ye 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.

Brenton⁽ⁱ⁾ ¹⁵ Seven days ye shall eat unleavened bread, and from the first day ye 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: ye shall do no servile work on them, only as many things as will necessarily be done by every soul, this only shall be done by you. ¹⁷ And ye shall keep this commandment, for on this day will I bring out your force out of the land of Egypt; and ye shall make this day a perpetual ordinance for you throughout your generations. ¹⁸ Beginning the fourteenth day of the first month, ye 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.
