Exodus 12:5–13

The lamb's blood on the doorposts spares Israel on the night of Passover

5Your lamb shall be without defect, a male, a year old; from the sheep or from the goats you shall take it.

6You shall keep it until the fourteenth day of this month, and the whole assembly of the community of Israel shall slaughter it at twilight.

7They shall take some of the blood and put it on the two doorposts and on the lintel of the houses in which they eat it.

8They shall eat the meat that night, roasted in fire, and unleavened bread; with bitter herbs they shall eat it.

9Do not eat any of it raw or boiled at all in water, but roasted in fire, its head with its legs and with its inner parts.

10You shall not leave any of it until morning; and what is left of it until morning you shall burn in the fire.

11This is how you shall eat it: your waists belted, your sandals on your feet, and your walking stick in your hand; and you shall eat it in haste. It is the Passover of YHWH.

12I will pass through the land of Egypt this night and strike every firstborn in the land of Egypt, both people and animals; and against all the gods of Egypt I will execute judgments. I am YHWH.

13The blood shall be a sign for you on the houses where you are; when I see the blood, I will pass over you, and no destroying plague will be among you when I strike the land of Egypt.

In its context

3Speak to all the community of Israel, saying, ‘On the tenth day of this month they shall take for themselves, each man, a lamb for each father’s house, a lamb for each household.

4If the household is too small for a lamb, then he and his neighbor nearest to his house shall take one according to the number of persons; you shall make your count for the lamb each according to what he eats.

…

14This day shall be for you a memorial, and you shall celebrate it as a festival to YHWH; throughout your generations, as a statute forever, you shall celebrate it.

15Seven days you shall eat unleavened bread. Indeed, on the first day you shall remove leaven from your houses, for whoever eats anything leavened, that person shall be cut off from Israel, from the first day until the seventh day.
