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 20

20:34 So Jonathan arose from the table in fierce anger, and did eat no meat the second day of the month: for he was grieved for David, because his father had done him shame.
