(29) Days of heaven.--Deuteronomy 11:21. (Comp. Psalm 72:5; and see below, Psalm 89:36.)

Verse 29. - His seed also will I make to endure forever (comp. 2 Samuel 7:16, "Thine house and thy kingdom shall be established forever before me"). And his throne as the days of heaven. "Thy throne shall be established forever;" "I will establish his kingdom" (2 Samuel 7:12, 16)

89:19-37 The Lord anointed David with the holy oil, not only as an emblem of the graces and gifts he received, but as a type of Christ, the King Priest, and Prophet, anointed with the Holy Ghost without measure. David after his anointing, was persecuted, but none could gain advantage against him. Yet all this was a faint shadow of the Redeemer's sufferings, deliverance, glory, and authority, in whom alone these predictions and promises are fully brought to pass. He is the mighty God. This is the Redeemer appointed for us, who alone is able to complete the work of our salvation. Let us seek an interest in these blessings, by the witness of the Holy Spirit in our hearts. As the Lord corrected the posterity of David for their transgressions, so his people shall be corrected for their sins. Yet it is but a rod, not a sword; it is to correct, not to destroy. It is a rod in the hand of God, who is wise, and knows what he does; gracious, and will do what is best. It is a rod which they shall never feel, but when there is need. As the sun and moon remain in heaven, whatever changes there seem to be in them, and again appear in due season; so the covenant of grace made in Christ, whatever alteration seems to come to it, should not be questioned.His seed also will I make to endure for ever,.... Not a race of kings from David, which ended at the Babylonish captivity; not the natural seed of David, not the Messiah himself, who sprung from him, but the Messiah's spiritual seed, which were given him by the Father, adopted through him, regenerated by his Spirit and grace, begotten through his Gospel, and the ministry of it, and born again in his church, and to whom he stands in the relation of the everlasting Father, Isaiah 9:6. The "enduring" of these "for ever" may denote the final perseverance of particular believers; which may be concluded from the relation of Christ, as an everlasting Father to them, who therefore must continue as his children; from his affection to them, from which there can be no separation; from their security in and by him, being in his hand, and in his heart; from their adoption, which is never revoked, being sons they are no more servants; from their regeneration of incorruptible seed; and from the nature of faith, which can never be lost: they that trust in the Lord are as Mount Zion, which endures for ever, Psalm 125:1 or it may be expressive of the duration of the church of Christ in general, throughout all periods of time, notwithstanding the malice and opposition of men and devils against it; see Matthew 16:18,

and his throne as the days of heaven; a phrase signifying a great length of time, Deuteronomy 11:21 yea, invariable constancy and duration, Jeremiah 31:25 and indeed the throne of Christ is for ever and ever, and will be when the present earth and heavens are fled away, Psalm 45:6. Christ is upon a throne now in heaven, the same with his divine Father's; and here he must sit and reign, till all enemies are put under him; and he will be on a throne of glory when he judges the world, and in the New Jerusalem state for the space of a thousand years; and, after that, he will reign with his saints, and they with him, for evermore; his throne and kingdom are everlasting, Isaiah 9:7.
