Instructions for the Passover and the Festival of Unleavened Bread
121The Lord told Moses and Aaron this in the land of Egypt:[] 2This month is to be the beginning of your calendar. It is to be the first month of the year for you. 3Tell the entire Israelite community that on the tenth day of this month, they are to take a lamb or a kid goat[] for themselves, according to their fathers' households, one lamb per household. 4But if the household is too small for a whole lamb, then that person and his neighbor next door to him must select one, based on the number of people. Determine what size lamb is needed according to how much each person will eat. 5Your lamb must be unblemished, a year-old male. You may take it from the sheep or the goats. 6You are to keep it until the fourteenth day of this month. Then the whole assembly of the Israelite community is to slaughter the lambs at sunset.[] 7They shall take some of the blood and put it on the two doorposts and the lintel of the houses where they eat the lamb. 8That night they shall eat the meat that has been roasted over a fire, along with unleavened bread. They shall eat it with bitter herbs. 9Do not eat it raw or boiled in water, but roasted over a fire, with its head, its legs, and its internal organs. 10You shall not leave any of it until the morning. Whatever remains until the morning, you shall burn in the fire. 11This is how you are to eat it: with your cloak tucked into your belt ready for travel,[] your sandals on your feet, and your staff in your hand. Eat it in haste. It is the Lord's Passover. 12For on that night I will pass through the land of Egypt. I will strike down every firstborn in the land of Egypt, both people and animals. Against all the gods of Egypt I will execute judgment. I am the Lord. 13The blood will be a sign for you on the houses where you are. When I see the blood, I will pass over you. There will be no plague among you to destroy you, when I strike down the land of Egypt.
14This day shall be a memorial for you, and you are to celebrate it as a festival to the Lord. Throughout your generations you must celebrate it as a permanent regulation. 15For seven days you shall eat unleavened bread. On the first day you must be sure to remove all yeast from your houses, for whoever eats anything leavened from the first day until the seventh day will be cut off from Israel. 16On the first day you are to have a holy convocation; also on the seventh day there is to be a holy convocation. You shall not do any work, except to prepare what everybody needs to eat. That is all you may do.
17You shall observe the Festival of Unleavened Bread, because on this very day I brought your divisions out from the land of Egypt. You shall observe this day throughout your generations as a permanent regulation. 18In the first month, you shall eat unleavened bread from the evening of the fourteenth day of the month until the evening of the twenty-first day of the month. 19No yeast is to be found in your houses for seven days, for whoever eats something leavened must be cut off from the Israelite community, whether a foreigner or native-born of the land. 20You shall not eat anything leavened. You shall eat unleavened bread in every place you live.
21Then Moses summoned all the elders of Israel and said to them, “Go and take lambs for yourselves according to your family size, and slaughter the Passover lamb. 22You shall take a bundle of hyssop, dip it in the blood that is in the basin, and paint the lintel and the two doorposts with the blood that is in the basin. None of you are to go out of the door of your house until morning. 23When the Lord passes through to strike Egypt and sees the blood on the lintel and the two doorposts, the Lord will pass over that door and will not allow the destroyer to enter your houses to strike you.
24“You shall observe these instructions as a perpetual regulation for you and your descendants. 25When you enter the land that the Lord will give you just as he said he would, you shall observe this ceremony. 26So when your children ask you, ‘What does this ceremony mean to you?’ 27you will say, ‘It is the sacrifice of the Passover to the Lord, who passed over the houses of the Israelites in Egypt. When he struck the Egyptians, he spared our houses.’”
The people bowed down and worshipped. 28The Israelites went and did all this. They did just as the Lord had commanded Moses and Aaron.
