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 15

15:8 For thy servant vowed a vow while I abode at Geshur in Syria, saying, If the LORD shall bring me again indeed to Jerusalem, then I will serve the LORD.
