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 24

24:1 And again the anger of the LORD was kindled against Israel, and he moved David against them to say, Go, number Israel and Judah.
