Exodus 12: 1 - 8, 11 - 14
1 The LORD said to Moses and Aaron in the land of Egypt,
2 "This month shall be for you the beginning of months; it shall be the first month of the year for you.
3 Tell all the congregation of Israel that on the tenth day of this month they shall take every man a lamb according to their fathers' houses, a lamb for a household;
4 and if the household is too small for a lamb, then a man and his neighbor next to his house shall take according to the number of persons; according to what each can eat you shall make your count for the lamb.
5 Your lamb shall be without blemish, a male a year old; you shall take it from the sheep or from the goats;
6 and you shall keep it until the fourteenth day of this month, when the whole assembly of the congregation of Israel shall kill their lambs in the evening.
7 Then they shall take some of the blood, and put it on the two doorposts and the lintel of the houses in which they eat them.
8 They shall eat the flesh that night, roasted; with unleavened bread and bitter herbs they shall eat it.
11 In this manner you shall eat it: your loins girded, your sandals on your feet, and your staff in your hand; and you shall eat it in haste. It is the LORD's passover.
12 For I will pass through the land of Egypt that night, and I will smite all the first-born in the land of Egypt, both man and beast; and on all the gods of Egypt I will execute judgments: I am the LORD.
13 The blood shall be a sign for you, upon the houses where you are; and when I see the blood, I will pass over you, and no plague shall fall upon you to destroy you, when I smite the land of Egypt.
14 "This day shall be for you a memorial day, and you shall keep it as a feast to the LORD; throughout your generations you shall observe it as an ordinance for ever.
