(3) The Rock of Israel.--Comp. 2Samuel 22:3. A frequent Scriptural comparison, appropriate here, to show the perfect reliability of what God declares.

He that ruleth.--The English gives the true sense, but the original is exceedingly elliptical, both here and in the following verse. The fundamental point of all just government has never been more perfectly set forth:--that it must be "in the fear of God."

Verses 3, 4. - He that ruleth, etc. This rendering of the Hebrew is very beautiful, and fit to be graven on the hearts of rulers. There is often almost an inspiration in the renderings of the Authorized Version. Grammatically, nevertheless, the psalm declares the blessedness of the king who is just, and may be translated as follows: -

"He that ruleth over men righteously,
That ruleth in the fear of God -
And as the morning light shall he be,
when the sun riseth,
A morning without clouds;
Yea, as the tender grass from the earth,
from sunshine, from rain." A king who rules his people justly is as glorious as the sun rising in its strength to drive away the works of darkness, and give men, by precept and example, the light of clear knowledge of their duty. But the last metaphor is especially beautiful. In the summer, vegetation dries up under the burning heat of the sun; all is bare and brown, and a few withered stalks of the coarser plants alone remain. But when the rains come, followed by bright sunshine, nature at one burst flashes into beauty, and the hillsides and plains are covered with the soft green of the reviving grass, through which myriads of flowers soon push their way, and clothe the landscape with bright colours. So a just and upright government calls into being countless forms of human activity, and fosters all that is morally beautiful, while it checks the blighting influences of unregulated passion and selfish greed.

23:1-7 These words of David are very worthy of regard. Let those who have had long experience of God's goodness, and the pleasantness of heavenly wisdom, when they come to finish their course, bear their testimony to the truth of the promise. David avows his Divine inspiration, that the Spirit of God spake by him. He, and other holy men, spake and wrote as they were moved by the Holy Ghost. In many things he had his own neglect and wrong conduct to blame. But David comforted himself that the Lord had made with him an everlasting covenant. By this he principally intended the covenant of mercy and peace, which the Lord made with him as a sinner, who believed in the promised Saviour, who embraced the promised blessing, who yielded up himself to the Lord, to be his redeemed servant. Believers shall for ever enjoy covenant blessings; and God the Father, Son, and Holy Ghost, shall be for ever glorified in their salvation. Thus pardon, righteousness, grace, and eternal life, are secured as the gift of God through Jesus Christ. There is an infinite fulness of grace and all blessings treasured up in Christ, for those who seek his salvation. This covenant was all David's salvation, he so well knew the holy law of God and the extent of his own sinfulness, that he perceived what was needful for his own case in this salvation. It was therefore all his desire. In comparison, all earthly objects lost their attractions; he was willing to give them up, or to die and leave them, that he might enjoy full happiness, Ps 73:24-28. Still the power of evil, and the weakness of his faith, hope, and love, were his grief and burden. Doubtless he would have allowed that his own slackness and want of care were the cause; but the hope that he should soon be made perfect in glory, encouraged him in his dying moments.The God of Israel said,.... To David, or by him; he who was the covenant God of Israel literally considered, and is the covenant God and Father of the whole spiritual Israel, and who is owned, believed in, and worshipped by them:

the Rock of Israel spake to me; the same with the God of Israel in other words, who is the strength and security of Israel; or the second divine Person, the Son and Word of God, is meant, who is often called a rock in Scripture; and is the rock on which the Israel or church of God is built, and in whom it remains safe and firm, the gates of hell not being able to prevail against it; and so here is an instance and proof of a trinity of persons in the Godhead; the God of Israel, Jehovah the Father; the Rock of Israel, Jehovah the Son; and the Spirit of Jehovah, as in 2 Samuel 23:2, who is Jehovah the Spirit: now what was said by these three divine Persons to David, and by him, and concerning himself as a type of the Messiah, follows:

he that ruleth over men must be just, ruling in the fear of God; which is a character every king among men ought to have, administering justice to their subjects; ruling not only according to the laws of the land, but according to the law of God; having his fear before their eyes, and acting with a view to his honour and glory, whose vicegerents they are, and to whom they are accountable; they should rule with gentleness and humanity, considering they are men, and not brutes, they rule over. Agamemnon in Homer is often called "king of men". This character, in all respects, was found in David, 2 Samuel 8:15; and may be here given as an instruction to his son and successor, Solomon; and is in all respects applicable to the Messiah, who is a "ruler" or King by the designation of his father; a ruler "over men", even over all men, yea, over the greatest of men, King of kings, and Lord of lords, and especially, and in an eminent sense, King of saints; and he is "just", a King that reigns in righteousness, righteous in all his ways and works, and particularly just as a King, as well as in all his other characters, see Jeremiah 23:5; and upon whom, as man and Mediator, the Spirit of "the fear of the Lord" rests, and under the influence of which, as such, he has acted, Isaiah 11:1; so the Targum applies these words to the Messiah thus,"the true Judge said, he would appoint to me a King, who is the Messiah, who shall arise and rule in the fear of the Lord:''and they may be rendered, there shall be "a ruler over men, just, ruling in the fear of God"; or ruling, appointing, ordering, and directing the worship of God, and the ordinances of it under the Gospel dispensation, as Christ did, see Matthew 28:18.
