New King James Version (NKJV)
Exodus 11
9 But the Lord said to Moses, "Pharaoh will not heed you, so that My wonders may be multiplied in the land of Egypt."
10 So Moses and Aaron did all these wonders before Pharaoh; and the Lord hardened Pharaoh’s heart, and he did not let the children of Israel go out of his land.
Exodus 12
1 Now the Lord spoke to Moses and Aaron in the land of Egypt, saying,
2 "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 tenth day 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 without blemish, a male of the first year. You may take it from the sheep or from the goats.
6 Now you shall keep it until the 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 night; roasted in fire, with unleavened bread and with bitter herbs they shall eat it.
9 Do not eat it raw, nor boiled at all with water, but roasted in fire--its head with its legs and its entrails.
