5Your lamb must be an unblemished year-old male, and you may take it from the sheep or the goats.
6You must keep it until the fourteenth day of the month, when the whole assembly of the congregation of Israel will slaughter the animals at twilight.
7They are to take some of the blood and put it on the sides and tops of the doorframes of the houses where they eat the lambs.
— Exodus 12:5-7
