21 Then Moses summoned all the elders of Israel and said to them, "Go, select an animal from the flock according to your families, and slaughter the Passover animal.  * 12:21 Ex 12:3; Mk 14:12–1622 Take a cluster of hyssop, dip it in the blood  * 12:22 Ex 12:7; Heb 11:28 that is in the basin, and brush the lintel and the two doorposts with some of the blood in the basin. None of you may go out the door of his house until morning. 23 When the Lord passes through to strike Egypt and sees the blood on the lintel and the two doorposts, he will pass over the door and not let the destroyer enter your houses to strike you.  * 12:23 Ezk 9:6; 1Co 10:10; Rv 7:3
