Psalm 89:29-37 ESV

I will establish his offspring forever and his throne as the days of the heavens. If his children forsake my law and do not walk according to my rules, if they violate my statutes and do not keep my commandments, then I will punish their transgression with the rod and their iniquity with stripes, but I will not remove from him my steadfast love or be false to my faithfulness. I will not violate my covenant or alter the word that went forth from my lips. Once for all I have sworn by my holiness; I will not lie to David. His offspring shall endure forever, his throne as long as the sun before me. Like the moon it shall be established forever, a faithful witness in the skies.” Selah
