He put his brother Abishai in charge of the rest of the troops. They organized for combat against the Ammonites.
Joab’s brother Abishai was the leader of the thirty. He used his spear to kill 300 men, but he was not one of the three,
Zeruiah’s son Abishai killed 18,000 Edomites in the Dead Sea region.
When Joab saw he was under attack in front and behind, he took the select troops of Israel and organized them for combat against the Arameans.
Joab said, “If the Arameans are too strong for my ⌞troops⌟, be ready to help me. And if the Ammonites are too strong for your ⌞troops⌟, I’ll help you.
The Ammonites formed a battle line at the entrance of the city, while the Arameans from Zobah and Rehob and the kings who had come remained by themselves in the open country.
