New Defender's Study Bible Notes
17:1 a ruinous heap. Damascus, a very ancient city, capital of the Syrians, was all but obliterated by the invading Assyrians.

17:7 his Maker. In the midst of this prophecy against Syria and its capital Damascus, there appears the prediction that ultimately the idolatrous Syrians would return to acknowledge that the God of Israel was their own Maker as well.
