7:1-9 God bears long, but he will not bear always with a provoking people. The remembrance of the mercies we formerly received, like the produce of the earth of the former growth, should make us submissive to the will of God, when we meet with disappointments in the latter growth. The Lord has many ways of humbling a sinful nation. Whatever trouble we are under, we should be most earnest with God for the forgiveness of sin. Sin will soon make a great people small. What will become of Israel, if the hand that should raise him be stretched out against him? See the power of prayer. See what a blessing praying people are to a land. See how ready, how swift God is to show mercy; how he waits to be gracious. Israel was a wall, a strong wall, which God himself reared as a defence to his sanctuary. The Lord now seems to stand upon this wall. He measures it; it appears to be a bowing, bulging wall. Thus God would bring the people of Israel to the trial, would discover their wickedness; and the time will come, when those who have been spared often, shall be spared no longer. But the Lord still calls Israel his people. The repeated prayer and success of the prophet should lead us to seek the Saviour.
9. 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 (Am 5:5; compare Ge 26:23, 24; 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. In the Hebrew here "Isaac" is written with s, instead of the usual ts; both forms mean "laughter"; the change of spelling perhaps expresses that their "high places of Isaac" may be well so called, but not as they meant by the name; for they are only fit to be laughed at in scorn. Probably, however, the mention of "Isaac" and "Israel" simply expresses that these names, which their degenerate posterity boasted in as if ensuring their safety, will not save them and their idolatrous "sanctuaries" on which they depended from ruin (compare Am 8:14).
