O God — It is evident, that the speech is still continued to the same person whom he calls king, Psalms 45:1, Psalms 45:11, and here God, to assure us that he doth not speak of Solomon, but a far greater king, who is not only a man, but the mighty God, Isaiah 9:6. A right scepter — Thou rulest with exact righteousness and equity.
