1 Samuel
Chapter
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
20:17 And Jonathan caused David to swear again, because he loved him: for he loved him as he loved his own soul.
