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

3:6 And it came to pass, while there was war between the house of Saul and the house of David, that Abner made himself strong for the house of Saul.
