Your lamb shall be without blemish, a male of the first year: ye shall take {it} out from the sheep, or from the goats: {of...: Heb. son of a year} 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. {in...: Heb. between the two evenings} 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.
