Shemot 12:14-15

Orthodox Jewish Bible

¹⁴ And hayom hazeh shall be unto you for zikaron (remembrance, remembering); and ye shall keep it a Chag (Feast) to Hashem throughout your generations; ye shall keep it a Chag (Feast) by a chukkat olam.

¹⁵ Shivat yamim shall ye eat matzot; but the first day ye shall put away se’or (yeast, leaven) out of your batim (houses); for whosoever eateth chametz from the first day until the seventh day, that nefesh shall be cut off from Yisroel.
