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 16

16:23 And the counsel of Ahithophel, which he counselled in those days, was as if a man had inquired at the oracle of God: so was all the counsel of Ahithophel both with David and with Absalom.
