21 Then Mosheh summoned the Israeli elders and told them, “Go ahead and select a lamb or young goat for each family and slaughter it. 22 Then you all must take a bunch of leafy hyssop stalks, and dip it in the basin with the blood from the sacrifice and paint the blood onto the lintel and both doorposts. After that, absolutely no one should go out the door of your houses until morning. 23 Then Yahweh will pass through out Egypt to strike the Egyptians and when he sees the blood on the lintel and on the two doorposts, he’ll ‘pass over’ that doorway and won’t permit ‘the destroyer’ to enter into your houses to strike.[ref] 24 All of you and your descendants must maintain this as a law and celebrate it forever, 25 so when you all enter into the land that Yahweh will give to you just as he promised, then you must observe this ceremony. 26 Then when it occurs, your children will ask, ‘What does this ceremony mean to you?’ 27 you all must tell them, ‘It’s the sacrifice of ‘pass-over’ to Yahweh, who passed over the houses of the Israelis in Egypt when he struck the Egyptians and rescued our families.’ ”

And the people bowed their heads and prostrated themselves, 28 and the Israelis went and did just as Yahweh had commanded through Mosheh and Aharon.
