'Door posts' in the Bible

by setting their threshold by My threshold and their doorpost beside My doorpost, with [only] the wall between Me and them. They have defiled and desecrated My holy name by the vile atrocities which they have committed. So I have consumed them in My anger.

The priest shall take some of the blood of the sin offering and put it on the door posts of the temple, on the four corners of the ledge of the altar, and on the posts of the gate of the inner courtyard.
