Amos 7:9

“And the high places of Isaac shall be desolate, etc.] Such as the ten tribes of Israel, who descended from Isaac, built at Beersheba, in imitation of Isaac, and pleading his example; who worshipped there, though not idols, as they, but the true God; and in commemoration of his being bound upon an altar on Mount Moriah: but these, as the Septuagint version renders it, were “high places of laughter”, ridiculous in the eyes of the Lord, despised by him, and so should be made desolate: and the sanctuaries of Israel shall be laid waste; the temples built for the calves at Daniel and Bethel, and other places: and I will rise against the house of Jeroboam with the sword; or, as the Targum, “I will…”

“high places--dedicated to idols. of Isaac--They boasted of their following the example of their forefather Isaac, in erecting high places at Beer-sheba (Amo 5:5; compare Gen 26:23-24; Gen 46:1); but he and Abraham erected them before the temple was appointed at Jerusalem--and to God; whereas they did so, after the temple had been fixed as the only place for sacrifices--and to idols.

His name was given from the joyous laughter at the unheard-of promise of God, to give children to those past age; their high places should be a laughter, but the laughter of mockery . The “sanctuaries” were perhaps the two great idol-temples at Bethel and Dan, over against the one “sanctuary” of God at Jerusalem; the “high places” were the shrines of idolatry, especially where God had…”

“The high places - The temples on high mountains built to idols. Of Isaac - The seed of Isaac. Amos 7:10”

“7:9 pagan shrines . . . temples: Every vestige of the apostate Israelite religion, from the common high places to the royal shrine at Bethel, would be destroyed. • of your ancestors (literally of Isaac): Isaac stands for Israel’s ancestors, the fathers of the nation. • dynasty of King Jeroboam: Jeroboam II died of natural causes (2 Kgs 14:29), but the murder of his son and successor, Zechariah, after a reign of less than a year (2 Kgs 15:8-10; see 2 Kgs 10:28-31), initiated instability in Israel’s government that it never overcame (2 Kgs 15:10-31).”

“the high: Amo 3:14, Amo 5:5, Amo 8:14, Beer-sheba, Gen 26:23-25, Gen 46:1; Lev 26:30, Lev 26:31 I will: Fulfilled, Kg2 15:8-10 Amos 7:10”
