{b} Depart from me, ye evildoers: for I will keep the commandments of my God.

(b) And hinder me not to keep the law of the Lord.

Jamieson-Fausset-Brown Bible Commentary

115-117. Hence he fears not wicked men, nor dreads disappointment, sustained by God in making His law the rule of life.

Depart from me-Ye can do nothing with me; for, &c. (Ps 6:8).

Matthew Henry's Concise Commentary

119:113-120 Here is a dread of the risings of sin, and the first beginnings of it. The more we love the law of God, the more watchful we shall be, lest vain thoughts draw us from what we love. Would we make progress in keeping God's commands, we must be separate from evil-doers. The believer could not live without the grace of God; but, supported by his hand, his spiritual life shall be maintained. Our holy security is grounded on Divine supports. All departure from God's statutes is error, and will prove fatal. Their cunning is falsehood. There is a day coming which will put the wicked into everlasting fire, the fit place for the dross. See what comes of sin Surely we who fall so low in devout affections, should fear, lest a promise being left us of entering into heavenly rest, any of us should be found to come short of it, Heb 4:1.

Matthew Henry's Whole Bible Commentary

Verse 115

Here is, 1. David's firm and fixed resolution to live a holy life: I will keep the commandments of my God. Bravely resolved! like a saint, like a soldier; for true courage consists in a steady resolution against all sin and for all duty. Those that would keep God's commandments must be often renewing their resolutions to do so: "I will keep them. Whatever others do, this I will do; though I be singular, though all about me be evil-doers, and desert me; whatever I have done hitherto, I will for the future walk closely with God. They are the commandments of God, of my God, and therefore I will keep them. He is God and may command me, my God and will command me nothing but what is for my good." 2. His farewell to bad company, pursuant to this resolution: Depart from me, you evil-doers. Though David, as a good magistrate, was a terror to evil-doers, yet there were many such, even about court, intruding near his person; these he here abdicates, and resolves to have no conversation with them. Note, Those that resolve to keep the commandments of God must have no society with evil-doers; for bad company is a great hindrance to a holy life. We must not choose wicked people for our companions, nor be intimate with them; we must not do as they do nor do as they would have us do, Ps. 1:1; Eph. 5:11.
