12 Then Yahweh told Mosheh and Aharon Egypt,[ref] 2 “This month is to become the beginning of the months for you all—from now on it will be the first month of the new year. 3 Assemble the people and tell them that on the tenth of this month, every man who’s the head of the household must select a lamb or young goat for his family. 4 But if the household’s too small to cook a whole animal, then neighbours can combine and share—budgeting on how much each person eats. 5 You all can choose either a sheep or a goat, but it must be a perfect, one-year-old male—without any defects. 6 You all must take special care of those animals until the fourteenth day of this month, then every Israeli household will slaughter their animal early that evening. 7 Then they must take some of the blood and put it on both doorposts and on the lintel of the houses that they’ll be in when they eat it. 8 They must roast them on the fire and eat the meat that night, along with flat bread and bitter herbs. 9 Don’t eat any of the meat raw and don’t boil it in water—it must be roasted over the fire with its head, legs, and internal organs. 10 Nothing must be left by morning—anything that’s not eaten must be burnt in the fire. 11 And this is how you all must eat it: with your belts fastened on your waists, your sandals on your feet, and your staffs in your hands. You all must eat it in a hurry. It is the Passover to Yahweh.

12 Then during that night, I will move throughout Egypt and I will kill all the oldest males—both people and animals. I will execute judgment on all the gods of Egypt. I am Yahweh. 13 That blood on the doorposts and lintel will be your sign on the houses which you are all in. I will see the blood and will pass over above you all, and the plague won’t affect you all with destruction as I strike against Egypt. 14 Then this day will become a memorial for you all, and you’ll celebrate it as a festival to Yahweh for future generations—a statute that you’ll all celebrate forever.[ref]

15 For seven days you all must only eat flat bread made without yeast. Yes, on the first day you all must remove any yeast from your houses, because anyone who eats bread with yeast during those seven days, that person must be permanently driven out of Israel. 16 On the first day, you all must gather for a sacred assembly, and similarly on the seventh day. No work can be done on those days other than meal preparation. 17 You all must regularly observe the Flat Bread Celebration, because on this very day I will have brought your divisions out from Egypt. You all must observe this day throughout future generations—a statute that you’ll all celebrate forever. 18 Starting on 14th of the first month in the evening, you all must eat only flat bread until the 21st day of the month in the evening. 19 For seven days you all must have no yeast in your homes, because anyone who eats bread with yeast in it, that person must be driven out from the Israeli people whether they’re a foreigner or a native. 20 You all mustn’t eat anything made with yeast. Wherever you live, you all must only eat flat bread.
