Psalm 89:3-4, 20-21, 29

You have said, “I have made a covenant with my chosen one; I have sworn to David my servant: ‘I will establish your offspring forever, and build your throne for all generations.’” Selah

I have found David, my servant; with my holy oil I have anointed him, so that my hand shall be established with him; my arm also shall strengthen him.

I will establish his offspring forever and his throne as the days of the heavens.
