'Rampart' in the Bible

The LORD hath purposed to destroy the wall of the daughter of Zion: he hath stretched out a line, he hath not withdrawn his hand from destroying: therefore he made the rampart and the wall to lament; they languished together.

Art thou better than populous No, that was situate among the rivers, that had the waters round about it, whose rampart was the sea, and her wall was from the sea?
