2 Samuel 10:9-11

Living Bible

⁹ When Joab realized that he would have to fight on two fronts, he selected the best fighters in his army, placed them under his personal command, and took them out to fight the Syrians in the fields. ¹⁰ He left the rest of the army to his brother Abishai, who was to attack the city.

¹¹ “If I need assistance against the Syrians, come out and help me,” Joab instructed him. “And if the Ammonites are too strong for you, I will come and help you.
