Exodus 12:15-17 seven days you eat matsah; surely the first day you shabbathize yeast from your houses: for whoever eats fermentation from the first day until the seventh day, that soul becomes cut off from Yisra El.

ECB⁽ⁱ⁾ ¹⁵ seven days you eat matsah; surely the first day you shabbathize yeast from your houses: for whoever eats fermentation from the first day until the seventh day, that soul becomes cut off from Yisra El. ¹⁶ And the first day is a holy convocation and the seventh day becomes a holy convocation to you; work not therein, except what every soul eat - only work that: ¹⁷ and guard the matsah; for in this selfsame day I bring your hosts from the land of Misrayim: and you guard this day in your generations by an eternal statute.
