9 And the Lord said unto Moses, Pharaoh will not hearken unto you; therefore my wonders shall be multiplied in the land of Egypt.
10 And Moses and Aaron did all these wonders before Pharaoh, and they went out from Pharaoh, and he was in great anger. And Pharaoh hardened his heart, so that he would not let the children of Israel go out of his land.
Exodus 12 Intro: The beginning of the year changed -- The passover instituted -- The firstborn slain -- The Israelites driven out.
1 And the Lord spake unto Moses and Aaron in the land of Egypt, saying,
2 This month shall be unto you the beginning of months; it shall be the first month of the year to you.
3 Speak ye unto all the congregation of Israel, saying, In the tenth day of this month they shall take to them every man a lamb, according to the house of their fathers, a lamb for a house;
4 And if the household be too little for the lamb, let him and his neighbor next unto his house take it according to the number of the souls; every man according to his eating shall make your count for the lamb.
5 Your lamb shall be without blemish, a male of the first year; ye shall take it out from the sheep, or from the goats;
6 And ye shall keep it up until the fourteenth day of the same month; and the whole assembly of the congregation of Israel shall kill it in the evening.
7 And they shall take of the blood, and strike it on the two side posts and on the upper doorpost of the houses, wherein they shall eat it.
8 And they shall eat the flesh in that night, roast with fire, and unleavened bread; and with bitter herbs they shall eat it.
