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.

1 Samuel 18

18:10 And it came to pass on the morrow, that the evil spirit from God came upon Saul, and he prophesied in the midst of the house: and David played with his hand, as at other times: and there was a javelin in Saul's hand.
