'Door posts' in the Bible

In their giving their threshold with my thresholds, and their door-post by my door-posts, and the wall between me and between them, and they defiled my holy name with their abominations which they did: and consuming them in my anger.

And the priest took of the blood of the sin and gave upon the door-posts of the house, and upon the four corners of the terrace, to the altar and upon the door-posts of the gate of the inner enclosure.

And the prince went in the way of the porch of the gate from without, and he stood by the door-posts of the gate, and the priests did his burnt-offerings and his peace, and he worshiped upon the threshold of the gate, and he went forth: and the gate shall not be shut until the evening.
