12:21 Then Moses summoned all the elders of Israel, and told them, “Go and select for yourselves a lamb or young goat for your families, and kill the Passover animals. 12:22 Take a branch of hyssop, dip it in the blood that is in the basin, and apply to the top of the doorframe and the two side posts some of the blood that is in the basin. Not one of you is to go out the door of his house until morning. 12:23 For the Lord will pass through to strike Egypt, and when he sees the blood on the top of the doorframe and the two side posts, then the Lord will pass over the door, and he will not permit the destroyer to enter your houses to strike you. 12:24 You must observe this event as an ordinance for you and for your children forever. 12:25 When you enter the land that the Lord will give to you, just as he said, you must observe this ceremony. 12:26 When your children ask you, ‘What does this ceremony mean to you?’ – 12:27 then you will say, ‘It is the sacrifice of the Lord’s Passover, when he passed over the houses of the Israelites in Egypt, when he struck Egypt and delivered our households.’” The people bowed down low to the ground, 12:28 and the Israelites went away and did exactly as the Lord had commanded Moses and Aaron.
