New Defender's Study Bible Notes
71:20 bring me up again. A life lived for the Lord will not end, nor will its testimony, even after death. There is ongoing life with the Lord beyond the grave, with future resurrection of the body also. In the meantime, “Thou shalt increase my greatness” (Psalm 71:21).
Psalm 72 (title). This psalm, like Psalm 2, does not list David as author in its heading, but its final verse confirms the Davidic authorship.
