All the words of my mouth are in righteousness,.... Or "with righteousness" (x); are connected with it, are agreeable to it; are righteous ones, consistent with righteousness, with the righteous nature, will, and law of God: or "are concerning righteousness" (y) the necessity of righteousness in order to eternal life; the insufficiency of man's own righteousness to entitle to it; the need, worth, and excellency of the righteousness of Christ for that purpose; and of the propriety and usefulness of a life of righteousness and holiness, which the grace of God instructs men in; there is nothing froward or perverse in them; that is contrary to right reason, or to the law of God, or to the Scriptures of truth, or to the analogy of faith; nor is there any contradiction in the doctrines of the Gospel one to another, but an entire harmony and uniformity in them; they are not "yea" and "nay". (x) "cum justitia", Piscator, Gejerus, Michaelis; , Sept. (y) "Gloriatio de justitia sua, vel invitatio ad accipiendam justitiam per fidem", Cocceius.
