You have said, “I have made a covenant with my chosen one; I have sworn to David my servant:
The writer of this psalm approaches God's throne with the covenant made to David as his anchor: God promised to sustain His favor toward this people forever through their king. He rehearses God's power in all creation and His faithfulness in redemption, yet the complaint that follows cuts sharp, God has seemingly abandoned His Church to her enemies, withdrawn all help and comfort, as though He had forgotten His own word.

Commenting on Psalm 89:1-52
I have made a covenant with my chosen, I have sworn unto David my servant. This was the ground of the Psalmist's confidence in God's mercy and truth, for he knew that the Lord had made a covenant of grace with David and his seed, and confirmed it by an oath.
The psalmist has a very sad complaint to make of the deplorable condition of the family of David at this time, and yet he begins the psalm with songs of praise; for we must, in every thing, in every state, give thanks; thus we must glorify the Lord in the fire.
