David’s kingdom of Judah
David becomes king of his own tribe
The map of Israel and Judah changed after Philistines killed King Saul and most of his sons in battle. David's tribe of Judah crowned him king of the powerful tribe. The other tribes up north and east of the Jordan River stayed with Saul's son Ishbosheth. He was a weak king, easily intimated by his commanding general, who seems to have slept with one of the woman in the king's herem. Not kosher. Initially, the general, Abner, supported Ishbosheth. He even went to battle against David, to defend the crown for Saul's family. But Abner lost to David's forces, and would later broker a deal to join forces with David.Battle for Israel and Judah
That didn't work out so well, David's general, Joab, murdered him. It was revenge for Abner reluctantly killing Joab's brother in battle. After the battle, Joab's brother, Asahel, who "ran like a wild gazelle," targeted Abner, who was retreating for home.Asahel refused to fight anyone else. He kept eyes on his bullseye, the enemy commander running away. Abner looked back and yelled, “Is that you, Asahel?” He said, “You bet it’s me.” Abner said, “Go after one of these other men and take what you want.” Asahel kept gaining on him. Abner said, “Pick someone else. I don’t want to kill you. If I do, how could I ever face your brother Joab?” Asahel kept running. He ran right into the butt end of Abner’s spear. It bore through his stomach and broke through his back. Asahel, David’s nephew, dropped dead. When fellow warriors came to his body, they stood for a time in silence. (2 Samul 2:19-23)Before long, the map of Israel and Judah would change again. David would unite the tribes and use the force of his armies to pacify Israel's neighbors.
