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

“I have made a covenant with My chosen; I have sworn to David My servant, I will establish your seed forever And build up your throne to all generations.” Selah.

I have found David My servant; With My holy oil I have anointed him, With whom My hand will be established; My arm also will strengthen him.

So I will establish his descendants forever And his throne as the days of heaven.
