'Door posts' in the Bible

And they took from the blood and gave upon the two door-posts, and upon the lintel within the houses which they shall eat it in them.

And take ye a bundle of hyssop, and dip in the blood that is upon the threshhold, and touch upon the lintel, and upon the two door-posts from the blood which is upon the threshhold and ye shall not come forth each from the door of his house till morning.

And Jehovah passed over to strike the Egyptians; and he saw the blood upon the lintel, and upon the two doorposts, and Jehovah passed by the door and will not give him destroying to come in to your houses to strike.
