New American Standard Bible (NASB)
Exodus 11
7 But against any of the sons of Israel a dog will not even bark, whether against man or beast, that you may understand how the Lord makes a distinction between Egypt and Israel.’
8 All these your servants will come down to me and bow themselves before me, saying, ’Go out, you and all the people who follow you,’ and after that I will go out." And he went out from Pharaoh in hot anger.
9 Then the Lord said to Moses, "Pharaoh will not listen to you, so that My wonders will be multiplied in the land of Egypt."
10 Moses and Aaron performed all these wonders before Pharaoh; yet the Lord hardened Pharaoh’s heart, and he did not let the sons of Israel go out of his land.
Exodus 12
1 Now the Lord said to Moses and Aaron in the land of Egypt,
2 "This month shall be the beginning of months for you; it is to be the first month of the year to you.
3 Speak to all the congregation of Israel, saying, ’On the tenth of this month they are each one to take a lamb for themselves, according to their fathers’ households, a lamb for each household.
4 Now if the household is too small for a lamb, then he and his neighbor nearest to his house are to take one according to the number of persons in them; according to what each man should eat, you are to divide the lamb.
5 Your lamb shall be an unblemished male a year old; you may take it from the sheep or from the goats.
6 You shall keep it until the fourteenth day of the same month, then the whole assembly of the congregation of Israel is to kill it at twilight.
7 Moreover, they 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.
