Exodus 12 King James Version (KJV)
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 an house:

4 And if the household be too little for the lamb, let him and his neighbour 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 door post of the houses, wherein they shall eat it.
