Psalms 102:28 - Joseph Benson’s Commentary on the Old and New Testaments

The children of thy servants shall continue Though the heavens and the earth perish, and though we, thy servants, pine away in our iniquities, according to thy righteous sentence and threatening, Leviticus 26:39, and die in captivity; yet, by virtue of thy eternal and unchangeable nature, and thy promises made to Abraham and his seed, we rest assured that our children, and their children after them, shall enjoy the promised mercies, even a happy restoration to and settlement in their own land, and the presence of our and their Messiah. And their seed shall be established before thee In the place of thy gracious presence, either here in thy church, or hereafter in heaven. Perhaps this expression, before thee, might be intended further to intimate, that their happiness did not consist in the enjoyment of the outward blessings of the land of Canaan, but in the presence and fruition of God there, which he mentions as the consummation of their desires and felicities.
