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 2

2:30 And Joab returned from following Abner: and when he had gathered all the people together, there lacked of David's servants nineteen men and Asahel.
