(Before It's News)
1 I will sing of thy steadfast love, O LORD, for ever; with my mouth I will proclaim thy faithfulness to all generations.
2 For thy steadfast love was established for ever, thy faithfulness is firm as the heavens.
3 Thou hast said, “I have made a covenant with my chosen one, I have sworn to David my servant:
4 `I will establish your descendants for ever, and build your throne for all generations.’” [Selah]
26 He shall cry to me, `Thou art my Father, my God, and the Rock of my salvation.’
28 My steadfast love I will keep for him for ever, and my covenant will stand firm for him.
