For the LORD will go about and smite Egypt. And when he seeth the blood upon the upper door post and on the two side posts, he will pass over the door and will not suffer the destroyer to come into your house to plague you.

And take a bunch of hyssop, and dip it in the blood that is in the basin, and strike it upon the upper post and on the two side posts, and see that none of you go out at the door of his house until the morning.

And when all the people saw the clouden pillar stand in the tabernacle door, they rose up and worshipped: every man in his tent door.
