Yahweh has purposed to destroy the wall of the daughter of Zion; He has stretched out the line, he has not withdrawn his hand from destroying; He has made the rampart and wall to lament; they languish together.
God was faithful to His warnings. He had told them if they did not turn from their wickedness, if they did not turn from their idolatry, that He was going to bring their enemies against them and they would be destroyed. God has done that which He had purposed.
