Exodus 12:22-24

New Living Translation

²² Drain the blood into a basin. Then take a bundle of hyssop branches and dip it into the blood. Brush the hyssop across the top and sides of the doorframes of your houses. And no one may go out through the door until morning. ²³ For the Lord will pass through the land to strike down the Egyptians. But when he sees the blood on the top and sides of the doorframe, the Lord will pass over your home. He will not permit his death angel to enter your house and strike you down.

²⁴ “Remember, these instructions are a permanent law that you and your descendants must observe forever.
