In 2 Samuel 3, the conflict between the house of David and the house of Saul continues. The chapter begins with a list of David's six sons, all born to him from different wives while he resided in Hebron. As David's power grows stronger, he becomes embroiled in a dispute with Abner, the commander of Saul's army, who seeks to bring all of Israel under David's rule.
Abner reaches out to David, proposing a covenant between them, which David agrees to. However, Joab, David's military commander, is suspicious of Abner's motives and secretly kills him in revenge for the death of his brother Asahel. David is devastated by Abner's death and publicly mourns, dissociating himself from Joab's actions.
David delivers a lament for Abner and acknowledges that Abner's death was a great loss for Israel. The people recognize David's innocence in the matter and perceive his deep sorrow. David also curses Joab and his descendants, praying that they would suffer from illnesses and violence.
Despite Abner's death, David continues to gain strength, and his influence over the tribes of Israel increases. His authority is recognized by the elders, and he gains more support. The chapter ends with a mention of David's growing number of wives and children, indicating his increasing power and status.
