[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.
