By the word of thy lips.--Some take this clause closely with the foregoing, and render, "against the word," &c; but the Authorised Version is better. The Divine standard for action, not the human or worldly, influences the writer.
I have kept me.--Literally, I for my part have observed ways of violence. But usage (Proverbs 2:20) almost compels us to understand by this, "I have kept ways of violence," which is impossible here. Hence we have either to give the verb the unusual sense "guard against," or suppose an error in the text.
by the word of thy lips; the law of God, the Scriptures of truth, the rule and standard of faith and practice, which show what works are good and what are not; by the use, help, and benefit of this;
I have kept me from the paths of the destroyer; such is the devil, who was a murderer from the beginning; antichrist, whose name is Abaddon and Apollyon, both which signify a destroyer; false teachers, and all wicked men: the "paths" of such are their wicked principles and practices, their damnable errors and heresies, their sins and lusts, which make up the broad road that leads to destruction: these the psalmist "kept" or "observed" (a), for the words "me" and "from" are not in the original text; and the sense is, that he took notice of them, and avoided them, and, as a faithful prince and magistrate, forbad his subjects walking in them, and restrained them from them, making the word of God the rule of his conduct.
