5 Your lamb shall be without blemish, a male of the first year: ye shall take it 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 at even. 7 And they shall take of the blood, and put it on the two side posts and on the lintel, upon the houses wherein they shall eat it.
