The first 20 chapters of 2 Samuel are divisible into four units each of which ends with a list of names that is four verses long (1:1-3:5; 3:6-5:16; 5:17-8:18; 9:1-20:26).2The first two units conclude with lists of David's sons that were born to him first in Hebron and then in Jerusalem. The second two units end with lists of David's officials. This structural division is helpful to observe because it clarifies the writer's intent in 2 Samuel: to provide a record of the consolidation of Israel's monarchy. The first three units are generally positive and describe David's triumphs whereas the last unit is generally negative and relates David's troubles.
In chapters 1-8 the writer's fertility motif reaches a climax in his description of David's reign. 1:1 and 8:13 form an inclusiothat surrounds this section.3
"The thesis of the author--that Israel is blessed with fertility when the nation (and the epitome of the nation, the king) is following the [Mosaic] covenant--is demonstrated in these chapters."4
