21 Moses called all the elders of Israel and said: »Take lambs according to your families and slay the Passover lamb.

22 »Take a bunch of hyssop and dip it in the blood that is in the basin. Apply some of the blood that is in the basin to the lintel and the two doorposts. No one shall go outside the door of his house until morning.

23 »Jehovah will pass through to strike the Egyptians. When he sees the blood on the top and sides of the doorframe, Jehovah will pass over the door and will not allow the destroyer to come in to your houses to kill you.
