The two Books of Samuel contain valuable historical material concerning the religious and moral conditions of the period. Samuel is the great prophet-judge who helps to unite the scattered tribes under one king, Saul. The history of the reigns of Saul and David is also recorded.

2 Samuel 8

8:18 And Benaiah the son of Jehoiada was over both the Cherethites and the Pelethites; and David's sons were chief rulers.
