EXO 12:22

22 and dip ye a bundle of hyssop, in the blood which is in the threshold, either in a vessel beside the threshold, and sprinkle ye thereof on the lintel, and ever either (door)post; none of you shall go out at the door of his house till the morrowtide. (and dip ye a bundle of hyssop in the blood which is on the threshold, or in a vessel beside the threshold, and sprinkle some of it on the lintel, and on both doorposts; and then none of you shall go out of the door of his house until the morning.)
