Leviticus 23 –
4 “‘These are the LORD’s appointed feasts, the sacred assemblies you are to proclaim at their appointed times: 5 The LORD’s Passover begins at twilight on the fourteenth day of the first month. 6 On the fifteenth day of that month the LORD’s Feast of Unleavened Bread begins; for seven days you must eat bread made without yeast. 7 On the first day hold a sacred assembly and do no regular work. 8 For seven days present an offering made to the LORD by fire. And on the seventh day hold a sacred assembly and do no regular work.’”
9 The LORD said to Moses, 10 “Speak to the Israelites and say to them: ‘When you enter the land I am going to give you and you reap its harvest, bring to the priest a sheaf of the first grain you harvest. 11 He is to wave the sheaf before the LORD so it will be accepted on your behalf; the priest is to wave it on the day after the Sabbath. 12 On the day you wave the sheaf, you must sacrifice as a burnt offering to the LORD a lamb a year old without defect, 13 together with its grain offering of two-tenths of an ephah of fine flour mixed with oil—an offering made to the LORD by fire, a pleasing aroma—and its drink offering of a quarter of a hin of wine. 14 You must not eat any bread, or roasted or new grain, until the very day youbring this offering to your God. This is to be a lasting ordinance for the generations to come, wherever you live.
Deuteronomy 16 –
1 Observe the month of Abib and celebrate the Passover of the LORD your God, because in the month of Abib he brought you out of Egypt by night. 2 Sacrifice as the Passover to the LORD your God an animal from your flock or herd at the place the LORD will choose as a dwelling for his Name. 3 Do not eat it with bread made with yeast, but for seven days eat unleavened bread, the bread of affliction, because you left Egypt in haste—so that all the days of your life you may remember the time of your departure from Egypt. 4 Let no yeast be found in your possession in all your land for seven days. Do not let any of the meat you sacrifice on the evening of the first day remain until morning.
5 You must not sacrifice the Passover in any town the LORD your God gives you 6 except in the place he will choose as a dwelling for his Name. There you must sacrifice the Passover in the evening, when the sun goes down, on the anniversary of your departure from Egypt. 7 Roast it and eat it at the place the LORD your God will choose. Then in the morning return to your tents. 8 For six days eat unleavened bread and on the seventh day hold an assembly to the LORD your God and do no work.
Exodus 12 –
1 The LORD said to Moses and Aaron in Egypt, 2 “This month is to be for you the first month, the first month of your year. 3 Tell the whole community of Israel that on the tenth day of this month each man is to take a lamb for his family, one for each household. 4 If any household is too small for a whole lamb, they must share one with their nearest neighbor, having taken into account the number of people there are. You are to determine the amount of lamb needed in accordance with what each person will eat. 5 The animals you choose must be year-old males without defect, and you may take them from the sheep or the goats. 6 Take care of them until the fourteenth day of the month, when all the people of the community of Israel must slaughter them at twilight. 7 Then they are to take some of the blood and put it on the sides and tops of the doorframes of the houses where they eat the lambs. 8 That same night they are to eat the meat roasted over the fire, along with bitter herbs, and bread made without yeast. 9 Do not eat the meat raw or cooked in water, but roast it over the fire—head, legs and inner parts. 10 Do not leave any of it till morning; if some is left till morning, you must burn it. 11 This is how you are to eat it: with your cloak tucked into your belt, your sandals on your feet and your staff in your hand. Eat it in haste; it is the LORD’s Passover.
12 “On that same night I will pass through Egypt and strike down every firstborn—both men and animals—and I will bring judgment on all the gods of Egypt. I am the LORD. 13 The blood will be a sign for you on the houses where you are; and when I see the blood, I will pass over you. No destructive plague will touch you when I strike Egypt.
14 “This is a day you are to commemorate; for the generations to come you shall celebrate it as a festival to the LORD—a lasting ordinance. 15 For seven days you are to eat bread made without yeast. On the first day remove the yeast from your houses, for whoever eats anything with yeast in it from the first day through the seventh must be cut off from Israel. 16 On the first day hold a sacred assembly, and another one on the seventh day. Do no work at all on these days, except to prepare food for everyone to eat—that is all you may do.
17 “Celebrate the Feast of Unleavened Bread, because it was on this very day that I brought your divisions out of Egypt. Celebrate this day as a lasting ordinance for the generations to come. 18 In the first month you are to eat bread made without yeast, from the evening of the fourteenth day until the evening of the twenty-first day. 19 For seven days no yeast is to be found in your houses. And whoever eats anything with yeast in it must be cut off from the community of Israel, whether he is an alien or native-born. 20 Eat nothing made with yeast. Wherever you live, you must eat unleavened bread.”
