Psalms 37:8

“I will keep thy statutes, etc.] This is a resolution taken up in the strength of divine grace, to answer the end of learning the judgments of God; which he did, not merely to have a notional knowledge of them, but to put them in practice; and not that he thought he could perfectly keep them, but was desirous of observing them in the best manner he could, as assisted by the grace of God; from love to God, in the faith and name of Christ, and with a view to the glory of God; without dependence upon them for life and salvation; O forsake me not utterly; totally and finally, or not at all; otherwise as if he should say, I shall never be able to keep thy statutes; so sensible was he of the…”

“Cease from anger - That is, in reference to the fact that there are wicked people, and that they are permitted to carry out their plans. Do not allow your mind to be excited with envious, fretful, wrathful, or murmuring feelings against God because he bears patiently with them, and because they are allowed a temporary prosperity and triumph. Be calm, whatever may be the wickedness of the world. The supreme direction belongs to God, and he will dispose of it in the best way. And forsake wrath - That is, as above, in regard to the existence of evil, and to the conduct of wicked men. Fret not thyself in any wise - See Psalms 37:1.

“Fret not - Either against the sinner for his success; or against God. Do evil - If grief arise in thee, take care that it do not transport thee to sin. Psalms 37:9”

“Cease: Job 5:2, Job 18:4; Pro 14:29, Pro 16:32; Eph 4:26, Eph 4:31; Jam 1:19, Jam 1:20, Jam 3:14-18 fret: Psa 31:22, Psa 73:15, Psa 116:11; Sa1 25:21-23; Jer 20:14, Jer 20:15; Jon 4:1, Jon 4:9; Luk 9:54, Luk 9:55 Psalms 37:9”

“On הרף (let alone), imper. apoc. Hiph., instead of הרפּה, vid., Ges. ֗75, rem. 15. אך להרע is a clause to itself (cf. Pro 11:24; Psa 21:5; Psa 22:16): it tends only to evil-doing, it ends only in thy involving thyself in sin. The final issue, without any need that thou shouldst turn sullen, is that the מרעים, like to whom thou dost make thyself by such passionate murmuring and displeasure, will be cut off, and they who, turning from the troublous present, make Jahve the ground and aim of their hope, shall inherit the land (vid., Psa 25:13). It is the end, the final and consequently eternal end, that decides the matter. Psalms 37:10”
