“The LORD hath purposed to destroy the wall of the daughter of Zion: he hath stretched out a line, he hath not withdrawn his hand from destroying: therefore he made the rampart and the wall to lament; they languished together.”
King James Version (KJV)
2:8 The wall - The strength and security of the Jews. A line - Artificers used with lines not only to mark out places for building, but also for destruction, to direct them what to cut off; and such a line is here meant.
