Exodus 12:5-7 World English Bible (WEB)
5 Your lamb shall be without defect, a male a year old. You shall take it from the sheep or from the goats. 6 You shall keep it until the fourteenth day of the same month; and the whole assembly of the congregation of Israel shall kill it at evening. 7 They shall take some of the blood, and put it on the two door posts and on the lintel, on the houses in which they shall eat it.
