7:9
And the high places of Isaac shall be desolate, and the sanctuaries of Israel shall be laid waste; and I will rise against the house of Jeroboam with the sword. KJV
{and the high things of idol shall be destroyed, and the hallowings of Israel shall be desolate; and I
shall rise on the house of Jeroboam by sword.} Wycliffe's Bible
And the high places of Isaac shall be desolate - Their total destruction is at hand. The high place of Isaac was Beer-sheba, where Isaac had built an altar to the Lord, ...This high place, which had been abused to idolatrous uses, was demolished by Josiah, king of Judah, ... for he defiled all the high places from Geba to Beersheba.
I will rise against the house of Jeroboam - The Lord had promised to Jehu, the ancestor of Jeroboam, that his family should sit on the throne of Israel to the fourth generation. Zechariah, the son of Jeroboam, was the fourth in order after Jehu; and on him the threatening in this verse fell; for he was murdered by Shallum after he had reigned six months, and in him the family became extinct.
