Exodus 12:21-23

Modern English Version

²¹ Then Moses called for all the elders of Israel and said to them, “Draw out and take for yourselves a lamb according to your families and kill the Passover lamb. ²² You shall take a bunch of hyssop, and dip it in the blood that is in the basin, and apply the lintel and the two side posts with the blood that is in the basin, and none of you shall go out from the door of his house until the morning. ²³ For the Lord will pass through to kill the Egyptians. And when He sees the blood upon the lintel and on the two side posts, the Lord will pass over the door and will not permit the destroyer to come to your houses to kill you.
