Ask of me, and I shall give you the nations for your inheritance, and the uttermost parts of the earth for your possession.
Read Chapter 2
Augustine of Hippo
AD 430
7. "Ask of Me, and I shall give Thee the nations for Thine inheritance" (ver. 8). This has at once a temporal sense with reference to the Manhood which He took on Himself, who offered up Himself as a Sacrifice in the stead of all sacrifices, who also maketh intercession for us; so that the words, "ask of Me," may be referred to all this temporal dispensation, which has been instituted for mankind, namely, that the "nations" should be joined to the Name of Christ, and so be redeemed from death, and possessed by God. "I shall give Thee the nations for Thine inheritance," which so possess them for their salvation, and to bear unto Thee spiritual fruit. "And the uttermost parts of the earth for Thy possession." The same repeated, "The uttermost parts of the earth," is put for "the nations;" but more clearly, that we might understand all the nations. And "Thy possession" stands for "Thine inheritance."
Ask. The Messias must be invested with human nature, and merit all graces for man. When did David ask for such an extensive dominion? (Berthier)
But Christ's kingdom extends over the world. His Church cannot fail, as St. Augustine proved hence against the Donatists, and his arguments confute Protestants as well. (Worthington)
Our doctors used to refer this psalm to the Messias, said R. Solomon; but it is better to apply it to David, on account of "Christians. "(Du Hamel)
