First & Second Chronicles- Everyman's Bible Commentary (Everyman's Bible Commentaries) / John Sailhamer

To its own generation the book of Chronicles was a vivid reminder of hope in the faithfulness of God, a reminder of the promise--made both to the world and to the house of David--of peace and prosperity, to be fulfilled through the covenant people of God.

Structurally, the book may be considered an exegetical summary of Old Testament history. Not only does it recount the important events of God's dealing with Israel, but it also explains the significance of those events to Israel's history.
