'Rampart' in the Bible

Jehovah hath purposed to destroy the wall of the daughter of Zion: he hath stretched out the line, he hath not withdrawn his hand from destroying; and he hath made the rampart and the wall to lament: they languish together.

Art thou better than No-Amon, that was situate among the rivers, that had the waters round about her, whose rampart was the sea, and of the sea was her wall?
