1 ADONAI spoke to Moshe and Aharon in the land of Egypt; he said, 2 “You are to begin your calendar with this month; it will be the first month of the year for you. 3 Speak to all the assembly of Isra’el and say, ‘On the tenth day of this month, each man is to take a lamb or kid for his family, one per household – 4 except that if the household is too small for a whole lamb or kid, then he and his next-door neighbor should share one, dividing it in proportion to the number of people eating it. 5 Your animal must be without defect, a male in its first year, and you may choose it from either the sheep or the goats. 6 “‘You are to keep it until the fourteenth day of the month, and then the entire assembly of the community of Isra’el will slaughter it at dusk. 7 They are to take some of the blood and smear it on the two sides and top of the door-frame at the entrance of the house in which they eat it. 8 That night, they are to eat the meat, roasted in the fire; they are to eat it with matzah and maror. 9 Don’t eat it raw or boiled, but roasted in the fire, with its head, the lower parts of its legs and its inner organs. 10 Let nothing of it remain till morning; if any of it does remain, burn it up completely. 11 “‘Here is how you are to eat it: with your belt fastened, your shoes on your feet and your staff in your hand; and you are to eat it hurriedly. It is ADONAI’s Pesach [Passover]. 12 For that night, I will pass through the land of Egypt and kill all the firstborn in the land of Egypt, both men and animals; and I will execute judgment against all the gods of Egypt; I am ADONAI. 13 The blood will serve you as a sign marking the houses where you are; when I see the blood, I will pass over [Hebrew: pasach] you – when I strike the land of Egypt, the death blow will not strike you. 14 “‘This will be a day for you to remember and celebrate as a festival to ADONAI; from generation to generation you are to celebrate it by a perpetual regulation.
