Exodus 12:22-24

Amplified Bible

²²You shall take a bunch of ^[a]hyssop, dip it in the blood which is in the basin, and touch some of the blood to the lintel [above the doorway] and to the two doorposts; and none of you shall go outside the door of his house until morning.

A Memorial of Redemption

²³For the Lord will pass through to strike the Egyptians; and when He sees the blood on the lintel [above the entry way] and on the two doorposts, the Lord will pass over the door and will not allow ^[b]the destroyer to come into your houses to slay you. ²⁴You shall observe this event [concerning Passover] as an ordinance for you and for your children forever.

Footnotes

Exodus 12:22 This evidently was a bristly plant which was useful as a kind of brush.
Exodus 12:23 Another translation is “the destruction,” which would make Yahweh (God) Himself, and not an “Angel of the Lord,” the One who either “passes over” (Ex 12:13) or “destroys.”

Exodus 12:22-24

New International Version

²²Take a bunch of hyssop,^(A) dip it into the blood in the basin and put some of the blood^(B) on the top and on both sides of the doorframe. None of you shall go out of the door of your house until morning. ²³When the Lord goes through the land to strike^(C) down the Egyptians, he will see the blood^(D) on the top and sides of the doorframe and will pass over^(E) that doorway, and he will not permit the destroyer^(F) to enter your houses and strike you down.
