This is simply "Of Solomon." The close is strikingly suited. "Blessed [be] Jehovah Elohim, the God of Israel alone doing wondrous things. And blessed [be] the name of his glory for ever; and let all the earth be filled with his glory. Amen and Amen. The prayers of David son of Jesse are ended."
It is evident that the psalm closes with the millennial reign of David's greater Son, the Messiah, to Whom God gives His judgments, and Who will glorify Him in His reign as He had in His rejection (72).
