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 19

19:32 Now Barzillai was a very aged man, even fourscore years old: and he had provided the king of sustenance while he lay at Mahanaim; for he was a very great man.
