Righteousness shall go before him. The word righteousness is taken by some for a righteous person; but this is unnatural. Viewed in this light, the passage, indeed, contains the useful and important truth, That the righteous man will walk before God, and will make it his object to regulate all his actions according to the principles of moral rectitude. But there being no necessity for wresting the word righteousness so violently, it will be better to adopt the more correct and simple view, which is, that under the reign of Christ order will be so well established, that righteousness will walk before God, and occupy every path. The prophet seems thus to call back the attention of the faithful to what constitutes the chief elements of blessedness; for although God may grant to his servants an abundant supply of sustenance for the body, it is unbecoming for them to have their hearts set upon this. And in truth, one difference between us and the lower animals is, that God, instead of pampering and stuffing our bellies, for the mere gratification of our animal appetites, directs our views to higher and more important objects. When it is said that righteousness shall go before God, the meaning is, that the prevalence and unobstructed course of righteousness, which is equivalent to setting her steps in the way, is to be attributed to the appointment of God. Isaiah, on the contrary, complains that equity, instead of setting her steps in the way, is prohibited from making her appearance in public, and meets with a universal repulse. "And judgment is turned away backward, and justice standeth afar off: for truth is fallen in the street, and equity cannot enter," (Isaiah 59:14.) In this psalm prayers and holy meditations, engaged in with the view of nourishing and confirming faith, together with praises and thanksgivings, are intermingled. It having been difficult in the judgment of carnal reason for David to escape from the distresses with which he was environed, he sets in opposition to its conclusions the infinite goodness and power of God. Nor does he simply request deliverance from his enemies; but he also prays that the fear of God may be implanted and firmly established in his heart.

Righteousness shall go before him - Shall anticipate his coming, and prepare his way. The idea seems to be, that in order to his appearing, there would be a proclamation of righteousness, and a preparation for his advent by the diffusion of righteousness among the people; in other words, the nation, in the prospect of his coming, would turn from sin, and would seek to be prepared for his appearing. Thus John proclaimed the coining of the Redeemer, "Repent ye, for the kingdom of heaven is at hand." Matthew 3:2. So also "The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight." Matthew 3:3.
And shall set us in the way of his steps - This might be rendered, "and set its steps for a way;" that is, the steps which would be taken by him would indicate the way in which his people should walk. Perhaps, however, the common interpretation best expresses the sense of the passage. According to that, the idea is, that the effect of his coming would be to dispose people to walk in the way of the steps which he took; to be his imitators and followers. The general thought is, that his coming would have the effect of turning the people to the paths of righteousness and truth. This is the designed effect of all the visitations of God to our world.

Righteousness shall go before him - Perhaps this verse may receive its best solution from Romans 3:25 : "Whom God hath set for a propitiation through faith in his blood, to declare his Righteousness for the remission of sins that are past." This term the apostle uses to point out God's method of justifying or saving mankind. And this, in the preaching of the pure Gospel, is ever going before to point out the Lord Jesus, and the redemption that is in his blood. And thus going before him, the sinner, who feels his need of salvation, is Set - in the way of his steps; as Bartimeus sat by the way-side begging, by which way Jesus walked; and when he came where he was, heard his prayer, and restored him his sight. Or, righteousness - the pure and holy law of God, must be proclaimed as broken by sinners, and calling aloud for vengeance, before they can see and feel their need of Christ crucified. By the preaching of the law they are prepared to receive the grace of the Gospel.

(h) Righteousness shall go before him; and shall set [us] in the way of his steps.
(h) Justice will then flourish and have free course and passage in every place.

Righteousness shall go before him,.... The incarnate Saviour, the increase of our land, and fruit of the virgin's womb; and righteousness may be put for a righteous person, as Aben Ezra interprets it; and may design John the Baptist, a holy and just man, Mark 6:20, who was the forerunner and harbinger of Christ, went before him, and prepared the way for him, Luke 1:76.
and shall set us in the way of his steps; the business of John the Baptist being not only to prepare the way of Christ by his doctrine and baptism, but to guide the feet of his people into the way of peace; or to direct them to believe in Christ, and to be followers of him, the Lamb of God, whithersoever he went; who has left an example of grace and duty, that we should tread in his steps, Luke 1:79, the Targum renders it, "in the good way"; and such a way John taught men to walk in.

Before him - As his harbinger. He shall fulfil all righteousness, he shall satisfy the righteousness of God, and shall advance righteousness and holiness among men. Set us - Shall cause us to walk in those righteous ways wherein he walketh.
