'Wall' in the Bible

My beloved is like a roe or a young hart: Behold, he standeth behind our wall; He looketh in at the windows; He glanceth through the lattice.

If she be a wall, We will build upon her a turret of silver: And if she be a door, We will inclose her with boards of cedar.

I am a wall, and my breasts like the towers thereof Then was I in his eyes as one that found peace.
