Charles Ellicott Commentary Amos 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." — Amos 7:9 (ASV)

High places of Isaac.— The name Isaac is here spelled somewhat differently in the Hebrew from the form we have in Genesis. The Septuagint misunderstands the word, and renders “altars of laughter,” in accordance with the etymological sense of the proper name. The residents in the neighborhood of Beersheba may have boasted of the favor or honor belonging to them, as occupying the home of Isaac and the birthplace of Jacob.

Will rise against.—This dreadful doom fell on the house of Jeroboam, and was the prelude to the final destruction of the nations by Shalmaneser IV., in 721 (2 Kings 15:10).
