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 3

3:30 So Joab and Abishai his brother slew Abner, because he had slain their brother Asahel at Gibeon in the battle.
