'Battlements' in the Bible

A day of trumpet and the battle cry [of invaders]Against the fortified citiesAnd against the high corner towers (battlements).

“I [the Lord] have cut off and destroyed nations [as a warning to Judah];Their corner towers (battlements) are in ruins.I have made their streets desolateSo that no one passes by;Their cities are destroyedSo that there is no man, there is no inhabitant.
