12:3Speak 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:

12:6And 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.

12:7And 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.
