New Defender's Study Bible Notes
51:4 have I sinned. There is no sin that injures only the sinner, and/or those he has wronged, for all sin is against God’s holy purpose for one’s life. David had certainly sinned against both Bathsheba and Uriah, but it was even a greater sin against God. This sin had “given great occasion to the enemies of the LORD to blaspheme” (II Samuel 12:14).
