the book of chronicles 1 is a really history based book show us the linage of the nation of Israel and its disorders at times up until the beginning of the reign of king David and the preparation of building of the temple.
the second book is talking about the constructing of the temple and reign of king Solomon i really love how in chapter 1 king Solomon prays for Wisdom , we also see the deportation of Babylon.
1st chronicles really shows the history,people and tribes and the preparations for the temple to be built even thought David would not be the one who would build it. How great it was that David asked only for wisdom to guide his people.
2nd chronicles Solomon starts and finished the temple his father David gathered almost all he would need to build and construct the temple both of these books go over things we learned in 1st & 2nd kings
