Exodus 12:5-7 Common English Bible (CEB)
5 Your lamb should be a flawless year-old male. You may take it from the sheep or from the goats. 6 You should keep close watch over it until the fourteenth day of this month. At twilight on that day, the whole assembled Israelite community should slaughter their lambs. 7 They should take some of the blood and smear it on the two doorposts and on the beam over the door of the houses in which they are eating.
