What does the Bible say about David's covenant with God?

In 2 Samuel 23:5, David acknowledges that although his household may not be in accordance with God, He has made with him an everlasting covenant which is ordered in all things and sure. This covenant represents God's sovereign grace and commitment to His people, indicating that salvation is solely founded on God's initiative and faithfulness rather than human merit. The everlasting nature of this covenant means it cannot be broken or altered, reflecting God's unchanging character and divine promises. This covenant ultimately points to Christ, who fulfills these promises on behalf of His people.
