Here, 1. He repeats the caution he had before given against envying the pleasures and successes of wicked man in their wicked ways. This he quotes from his father David, Psa 37:1. We must not in any case fret ourselves, or make ourselves uneasy, whatever God does in his providence how disagreeable soever it is to our sentiments, interests, and expectations, we must acquiesce in it. Even that which grieves us must not fret us; nor must our eye be evil against any because God is good. Are we more wise or just than he? If wicked people prosper, we must not therefore incline to do as they do. 2. He gives a reason for this caution, taken from the end of that way which wicked man walk in. Envy not their prosperity; for, (1.) There is no true happiness in it: Thee shall be no reward to the evil man; his prosperity only serves for his present subsistence; these are all the good things he must ever expect: there is none intended him in the world of retribution. He has his reward, Mat 6:2. He shall have none. Those are not to be envied that have their portion in this life and must out-live it, Psa 17:14. (2.) There is no continuance in it; their candle shines brightly, but it shall presently be put out, and a final period put to all their comforts, Job 21:14; Psa 37:1, Psa 37:2.
