11 He now begins to refer to the promise that were made by God to David his father, in the hope of more easily obtaining what he asks for through such reference, as he seems to demand it as a debt fairly due. “The Lord hath sworn truth to David;” as much as to say, David, having sworn to the Lord, that he would build a temple to his glory, and the Lord swore, in return, that he would establish the sovereign power in David’s family for all eternity; for God will not be outdone in liberality, and rewards
Psalm 131:11
