Commentary for Psalms 89:3

For I said, “Forever will it be built with kindness” For I said, “Forever the throne of David will be built with kindness,” as it is said (II Sam. 7:13): “and I shall establish the throne of his kingdom, etc.” Another explanation: I thought that the world would be built with Your kindness and that You would establish Your faithfulness in the heavens, to be established and made permanent. Now what is the faithfulness? That promise You promised David through Nathan the prophet, saying, “I formed a covenant with My chosen one to establish his seed until eternity.”
