And I the LORD will be their God, and my servant David a prince among them; I the LORD have spoken it.
I the Lord will be their God, and my servant David a prince among them - "my servant" implying fitness for ruling in the name of God, not pursuing a self-chosen course, as other kings, but acting as the faithful administrator of the will of God; Messiah realized fully this character (Psalms 40:7-8; Isaiah 42:1; Isaiah 49:3; Isaiah 49:6; Isaiah 53:11; Philippians 2:7), which David typically and partially represented (Acts 13:36); so He is the fittest person to wield the world-sceptre, abused by all the world-kings (Daniel 2:34-35; Daniel 2:44-45).
