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 23

23:13 And three of the thirty chief went down, and came to David in the harvest time unto the cave of Adullam: and the troop of the Philistines pitched in the valley of Rephaim.
