Psalm 89:1-4, 26-29

Your love, O Lord, forever will I sing; from age to age my mouth will proclaim your faithfulness.

For I am persuaded that your love is established for ever; you have set your faithfulness firmly in the heavens.

“I have made a covenant with my chosen one; I have sworn an oath to David my servant:

‘I will establish your line for ever, and preserve your throne for all generations.'”

…

He will say to me, ‘You are my Father, my God, and the rock of my salvation.’

I will make him my firstborn and higher than the kings of the earth.

I will keep my love for him forever, and my covenant will stand firm for him.

I will establish his line for ever and his throne as the days of heaven.”
