God's Purposes

"Solomon adds an argument ad hominem - addressed to the individual: “Thou canst not do a greater kindness to thy enemy, when he has fallen, than to rejoice in it; for them, to cross thee and vex thee, God will turn his wrath from him; for, as the wrath of man works not the righteousness of God, so the righteousness of God was never intended to gratify the wrath of man, and humour his foolish passions; rather than seem to do that he will adjourn the execution of his wrath: nay, it is implied that when he turns his wrath from him he will turn it against thee and the cup of trembling shall be put into thy hand.” - Matthew Henry
