Exodus 12:13 YLT

¹¹  'And thus ye do eat it: your loins girded, your sandals on your feet, and your staff in your hand, and ye have eaten it in haste; it is Jehovah's passover,

¹²  and I have passed over through the land of Egypt during this night, and have smitten every first-born in the land of Egypt, from man even unto beast, and on all the gods of Egypt I do judgments; I 'am' Jehovah.

¹³  'And the blood hath become a sign for you on the houses where ye 'are', and I have seen the blood, and have passed over you, and a plague is not on you for destruction in My smiting in the land of Egypt.

¹⁴  'And this day hath become to you a memorial, and ye have kept it a feast to Jehovah to your generations; -- a statute age-during; ye keep it a feast.

¹⁵  Seven days ye eat unleavened things; only -- in the first day ye cause leaven to cease out of your houses; for any one eating anything fermented from the first day till the seventh day, even that person hath been cut off from Israel.
