2. The prediction is of utter ruin, v. 9. (1.) The body of the people shall be destroyed, with all those things that were their ornament and defence. They are here called Isaac as well as Israel, the house of Isaac (v. 16), some think in allusion to the signification of Isaac's name; it is laughter; they shall become a jest among all their neighbours; their neighbours shall laugh at them. The desolation shall fasten upon their high places and their sanctuaries, either their castles or their temples, both built on high places. Their castles they thought safe, and their temples sacred as sanctuaries. These shall be laid waste, to punish them for their idolatry and to make them ashamed of their carnal confidences, which were the two things for which God had a controversy with them. When these were made desolate they might read their sin and folly in their punishment. (2.) The royal family shall sink first, as an earnest of the ruin of the whole kingdom: I will rise against the house of Jeroboam, Jeroboam the second, who was now king of the ten tribes; his family was extirpated in his son Zecharias, who was slain with the sword before the people, by Shallum who conspired against him, 2 Kings xv. 10. How unrighteous soever the instruments were, God was righteous, and in them God rose up against that idolatrous family. Even king's houses will be no shelter against the sword of God's wrath.
