I will sing of your steadfast love, O Lord, for ever;
   with my mouth I will proclaim your faithfulness to all generations. 
I declare that your steadfast love is established for ever;
   your faithfulness is as firm as the heavens. 
You said, ‘I have made a covenant with my chosen one,
   I have sworn to my servant David: 
“I will establish your descendants for ever,
   and build your throne for all generations.” ’

Psalm 89:1–4
