This psalm is by some ascribed to Moses, by others to David, which latter is more probable; with which agree the Septuagint, Vulgate Latin, and all the Oriental versions; all which, excepting the Syriac and Arabic versions, say it is a psalm that was made to be sung the day before the sabbath; and it was a custom with the Jews {a} to sing it on the sixth day of the week; which it is likely the authors of the Septuagint version were acquainted with, and therefore inserted it in the title of the psalm, though it is not in the Hebrew text. The subject of the psalm is the kingdom of God; not of nature and providence, but of grace; the kingdom of the Messiah; of the certainty, firmness, and eternity of it, notwithstanding the opposition of mighty enemies; being established by the sure promises of God, which his faithfulness and holiness were engaged to make good. Kimchi says, that all these psalms, this and the following to Psalm 101, are concerning the Messiah; and so say Kabvenaki and Ben Melech.
