Ask of me, &c.— This, as it refers to David, denotes God's promise to extend his dominion over all the neighbouring states and princes that opposed him, around all the borders of Judaea; and this promise was literally made good. But this extent of dominion is too small to come up to the full meaning of the expressions here made use of, which were more amply fulfilled in his great successor the Messiah, to whom God put all things in subjection in heaven and earth, and who shall finally crush, as with an iron rod, all who will not have him to reign over them. Some writers have supposed, that the ninth verse more immediately alludes to the final destruction of Jerusalem, and the dispersion of the Jews.
