The LORD said to Moses and Aaron in the land of Egypt,
1 “This month shall stand at the head of your calendar; you shall reckon it the first month of the year.
Tell the whole community of Israel: On the tenth of this month every one of your families must procure for itself a lamb, one apiece for each household.
2 If a family is too small for a whole lamb, it shall join the nearest household in procuring one and shall share in the lamb in proportion to the number of persons who partake of it.
The lamb must be a year-old male and without blemish. You may take it from either the sheep or the goats.
You shall keep it until the fourteenth day of this month, and then, with the whole assembly of Israel present, it shall be slaughtered during the evening twilight.
They shall take some of its blood and apply it to the two doorposts and the lintel of every house in which they partake of the lamb.
That same night they shall eat its roasted flesh with unleavened bread and bitter herbs.
It shall not be eaten raw or boiled, but roasted whole, with its head and shanks and inner organs.
None of it must be kept beyond the next morning; whatever is left over in the morning shall be burned up.
3 “This is how you are to eat it: with your loins girt, sandals on your feet and your staff in hand, you shall eat like those who are in flight. It is the Passover of the LORD.
For on this same night I will go through Egypt, striking down every first – born of the land, both man and beast, and executing judgment on all the gods of Egypt-I, the LORD!
But the blood will mark the houses where you are. Seeing the blood, I will pass over you; thus, when I strike the land of Egypt, no destructive blow will come upon you.
“This day shall be a memorial feast for you, which all your generations shall celebrate with pilgrimage to the LORD, as a perpetual institution.
For seven days you must eat unleavened bread. From the very first day you shall have your houses clear of all leaven. Whoever eats leavened bread from the first day to the seventh shall be cut off from Israel.
On the first day you shall hold a sacred assembly, and likewise on the seventh. On these days you shall not do any sort of work, except to prepare the food that everyone needs.
“Keep, then, this custom of the unleavened bread. Since it was on this very day that I brought your ranks out of the land of Egypt, you must celebrate this day throughout your generations as a perpetual institution.
From the evening of the fourteenth day of the first month until the evening of the twenty-first day of this month you shall eat unleavened bread.
For seven days no leaven may be found in your houses. Anyone, be he a resident alien or a native, who eats leavened food shall be cut off from the community of Israel.
Nothing leavened may you eat; wherever you dwell you may eat only unleavened bread.”
Moses called all the elders of Israel and said to them, “Go and procure lambs for your families, and slaughter them as Passover victims.
4 Then take a bunch of hyssop, and dipping it in the blood that is in the basin, sprinkle the lintel and the two doorposts with this blood. But none of you shall go outdoors until morning.
For the LORD will go by, striking down the Egyptians. Seeing the blood on the lintel and the two doorposts, the LORD will pass over that door and not let the destroyer come into your houses to strike you down.
“You shall observe this as a perpetual ordinance for yourselves and your descendants.
Thus, you must also observe this rite when you have entered the land which the LORD will give you as he promised.
When your children ask you, ‘What does this rite of yours mean?’
you shall reply, ‘This is the Passover sacrifice of the LORD, who passed over the houses of the Israelites in Egypt; when he struck down the Egyptians, he spared our houses.'” Then the people bowed down in worship,
and the Israelites went and did as the LORD had commanded Moses and Aaron.
At midnight the LORD slew every first-born in the land of Egypt, from the first-born of Pharaoh on the throne to the first-born of the prisoner in the dungeon, as well as all the first-born of the animals.
Pharaoh arose in the night, he and all his servants and all the Egyptians; and there was loud wailing throughout Egypt, for there was not a house without its dead.
During the night Pharaoh summoned Moses and Aaron and said, “Leave my people at once, you and the Israelites with you! Go and worship the LORD as you said.
Take your flocks, too, and your herds, as you demanded, and be gone; and you will be doing me a favor.”
The Egyptians likewise urged the people on, to hasten their departure from the land; they thought that otherwise they would all die.
The people, therefore, took their dough before it was leavened, in their kneading bowls wrapped in their cloaks on their shoulders.
The Israelites did as Moses had commanded: they asked the Egyptians for articles of silver and gold and for clothing.
The LORD indeed had made the Egyptians so well-disposed toward the people that they let them have whatever they asked for. Thus did they despoil the Egyptians.
The Israelites set out from Rameses for Succoth, about six hundred thousand men on foot, not counting the children.
5 A crowd of mixed ancestry also went up with them, besides their livestock, very numerous flocks and herds.
Since the dough they had brought out of Egypt was not leavened, they baked it into unleavened loaves. They had been rushed out of Egypt and had no opportunity even to prepare food for the journey.
6 The time the Israelites had stayed in Egypt was four hundred and thirty years.
At the end of four hundred and thirty years, all the hosts of the LORD left the land of Egypt on this very date.
This was a night of vigil for the LORD, as he led them out of the land of Egypt; so on this same night all the Israelites must keep a vigil for the LORD throughout their generations.
The LORD said to Moses and Aaron, “These are the regulations for the Passover. No foreigner may partake of it.
However, any slave who has been bought for money may partake of it, provided you have first circumcised him.
But no transient alien or hired servant may partake of it.
7 It must be eaten in one and the same house; you may not take any of its flesh outside the house. You shall not break any of its bones.
The whole community of Israel must keep this feast.
If any aliens living among you wish to celebrate the Passover of the LORD, all the males among them must first be circumcised, and then they may join in its observance just like the natives. But no man who is uncircumcised may partake of it.
The law shall be the same for the resident alien as for the native.”
All the Israelites did just as the LORD had commanded Moses and Aaron.
On that same day the LORD brought the Israelites out of Egypt company by company.
1  This month: Abib, the month of “ripe grain.” Cf ⇒ Exodus 13:4; ⇒ 23:15; ⇒ 34:18; ⇒ Deut 16:1. It occurred near the vernal equinox, March-April. Later it was known by the Babylonian name of Nisan. Cf ⇒ Nehemiah 2:1; ⇒ Esther 5:7.
2  Share in the lamb: probably, in the expenses of its purchase. Some explain, “reckon for the lamb the number of persons required to eat it.” Cf ⇒ Exodus 12:10.
3  Passover: in Hebrew, pesach, in Aramaic, pascha. In the following verses the same root is used in the verb “to pass over.” The word may be originally Egyptian, pesach, “the blow,” i.e., the final plague which destroyed the Egyptian first-born.
4  Hyssop: a plant with many woody branchlets that made a convenient sprinkler.
6  In Egypt: according to some ancient sources, “in Canaan and Egypt,” thus reckoning from the time of Abraham. Cf ⇒ Gal 3:17.
7  You shall not break any of its bones: the application of these words to our Lord on the cross shows that the Paschal lamb was a prophetic type of Christ, immolated to free men from the bondage of sin. Cf also ⇒ 1 Cor 5:7; ⇒ 1 Peter 1:19.
