'Door post' in the Bible

In their putting their threshold with My threshold, And their door-post near My door-post, And the wall between Me and them, And they have defiled My holy name, By their abominations that they have done, And I consume them in Mine anger.

and the priest hath taken of the blood of the sin offering, and hath put on the door-post of the house, and on the four corners of the border of the altar, and on the post of the gate of the inner court.
