Here David prays for two great spiritual blessings, and is, in this verse, as earnest for the good work of God in him as, in the verse before, for the good-will of God towards him. He prays, 1. For direction in the paths of duty: "Order my steps in thy word; having led me into the right way, let every step I take in that way be under the guidance of thy grace." We ought to walk by rule; all the motions of the soul must not only be kept within the bounds prescribed by the word, so as not to transgress them, but carried out in the paths prescribed by the word, so as not to trifle in them. And therefore we must beg of God that by his good Spirit he would order our steps accordingly. 2. For deliverance from the power of sin: "Let no iniquity have dominion over me, so as to gain my consent to it, and that I should be led captive by it." The dominion of sin is to be dreaded and deprecated by every one of us; and, if in sincerity we pray against it, we may receive that promise as an answer to the prayer (Rom 6:14), Sin shall not have dominion over you.

TZADDI.--The Eighteenth Part.

TZADDI. Righteous art thou, O Lord,.... Essentially, originally, and of himself; naturally, immutably, and universally, in all his ways and works of nature and grace; in his thoughts, purposes, counsels, and decrees; in all the dispensations of his providence; in redemption, in the justification of a sinner, in the pardon of sin, and in the gift of eternal life through Christ;

and upright are thy judgments; they are according to the rules of justice and equity; the precepts of the word, the doctrines of the Gospel, as well as the judgments of God inflicted on wicked men, and all the providential dealings of God with his people, and also the final judgment.
