“I will sing of the steadfast love of the Lord, forever; with my mouth I will make known your faithfulness to all generations. For I said, “Steadfast love will be built up forever; in the heavens you will establish your faithfulness.” 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”
Psalm 89:1-4 ESV
