Exodus 12:21-28 Then Moses summoned all the elders of Israel and told them, “Choose sheep for your families, and slaughter the Passover lamb.

ISV⁽ⁱ⁾ ²¹ Then Moses summoned all the elders of Israel and told them, “Choose sheep for your families, and slaughter the Passover lamb. ²² Take a bundle of hyssop and dip it in the blood that is in the basin, and apply some of the blood in the basin to the lintel and the two doorposts. None of you is to go out of the doorway of his house until morning, ²³ because the LORD will pass through to strike down the Egyptians, and when he sees the blood on the lintel and the two doorposts, the LORD will pass over the doorway, and won’t allow the destroyer to enter your houses to strike you down. ²⁴ You are to observe this event as a perpetual ordinance for you and your children forever. ²⁵ When you enter the land that the LORD will give you, just as he promised, you are to observe this ritual. ²⁶ And when your children say to you, ‘What does this ritual mean?’ ²⁷ you are to say, ‘It is the Passover sacrifice to the LORD, who passed over the houses of the Israelis in Egypt when he struck down the Egyptians but spared our houses.’” Then the people bowed down and worshipped. ²⁸ The Israelis did this. Moses and Aaron did just what the LORD had commanded.
