Exodus 12:1-13
The Passover
1 Now the LORD spoke to Moses and Aaron in the land of Egypt, saying, 2 a "This month shall be your beginning of months; it shall be the first month of the year to you. 3 "Speak to all the congregation of Israel, saying: 'On the b tenth of this month every man shall take for himself a lamb, according to the house of his father, a lamb for a household. 4 'And if the household is too small for the lamb, let him and his neighbor next to his house take it according to the number of the persons; according to each man's need you shall make your count for the lamb. 5 'Your lamb shall be c without 1 blemish, a male 2 of the first year. You may take it from the sheep or from the goats. 6 'Now you shall keep it until the d fourteenth day of the same month. Then the whole assembly of the congregation of Israel shall kill it at twilight.
7 'And they shall take some of the blood and put it on the two doorposts and on the lintel of the houses where they eat it. 8 'Then they shall eat the flesh on that e night; f roasted in fire, with g unleavened bread and with bitter herbs they shall eat it. 9 'Do not eat it raw, nor boiled at all with water, but h roasted in fire - its head with its legs and its entrails. 10 i 'You shall let none of it remain until morning, and what remains of it until morning you shall burn with fire. 11 'And thus you shall eat it: 3 with a belt on your waist, your sandals on your feet, and your staff in your hand. So you shall eat it in haste. j It is the LORD's Passover. 12 'For I k will pass through the land of Egypt on that night, and will strike all the firstborn in the land of Egypt, both man and beast; and l against all the gods of Egypt I will execute judgment: m I am the LORD. 13 'Now the blood shall be a sign for you on the houses where you are. And when I see the blood, I will pass over you; and the plague shall not be on you to destroy you when I strike the land of Egypt.
