‏ Psalms 89:29-38

Verse 29. His seed also will I make to endure for ever] This can apply only to the spiritual David. The posterity of David are long since extinct, or so blended with the remaining Jews as to be utterly indiscernible; but Jesus ever liveth, and his seed (Christians) are spread, and are spreading over all nations; and his throne is eternal. As to his manhood, he is of the house and lineage of David; the government is upon his shoulders, and of its increase there shall be no end, upon the throne of David and on his kingdom to order it and to establish it with judgment and justice, from henceforth even for ever. Isa 9:7.

Verse 30. If his children forsake my law] See Clarke on 2Sa 7:13, where this and some of the following verses are explained.

Verse 34. My covenant will I not break] My determination to establish a spiritual kingdom, the head of which shall be Jesus, the son of David, shall never fail. My prophets have declared this, and I will not alter the thing that is gone out of my mouth.

Verse 35. Once have I sworn] I have made one determination on this head, and have bound myself by my holiness; it is impossible that I should change, and there needs no second oath, the one already made is of endless obligation.

Verse 36. His throne as the sun] Splendid and glorious! dispensing light, heat, life, and salvation to all mankind.

Verse 37. As the moon, and as a faithful witness in heaven.] That is, as long as the sun and moon shall endure, as long as time shall last, his kingdom shall last among men. The moon appears to be termed a faithful witness here, because by her particularly time is measured. Her decrease and increase are especially observed by every nation, and by these time is generally estimated, especially among the eastern nations. So many moons is a man old; so many moons since such an event happened; and even their years are reckoned by lunations. This is the case with the Mohammedans to the present day. Or the rainbow may be intended; that sign which God has established in the cloud; that faithful witness of his that the earth shall no more be destroyed by water. As long therefore as the sun, the moon, and the rainbow appear in the heavens, so long shall the spiritual David reign, and his seed prosper and increase.

Selah.] It is confirmed; it shall not fail.

Verse 38. But thou hast cast off] Hitherto the psalmist has spoken of the covenant of God with David and his family, which led them to expect all manner of prosperity, and a perpetuity of the Jewish throne; now he shews what appears to him a failure of the promise, and what he calls in the next verse the making void the covenant of his servant. God cannot lie to David; how is it then that his crown is profaned, that it is cast down to the ground; the land being possessed by strangers, and the twelve tribes in the most disgraceful and oppressive captivity?
