10:8 The Ammonites marched out and were deployed for battle at the entrance of the city gate, while the men from Aram Zobah, Rehob, Ish-tob, and Maacah were by themselves in the field.
10:9 When Joab saw that the battle would be fought on two fronts, he chose some of Israel’s best men and deployed them against the Arameans.
