2 Samuel 10:5-12

When all this was reported to David, he sent someone to meet them, for they were seriously humiliated. The king told them, “Stay in Jericho until your beards grow out. Only then come back.” When it dawned on the Ammonites that as far as David was concerned they stunk to high heaven, they hired Aramean soldiers from Beth-Rehob and Zobah—twenty thousand infantry—and a thousand men from the king of Maacah, and twelve thousand men from Tob. When David heard of this, he dispatched Joab with his strongest fighters in full force. The Ammonites marched out and arranged themselves in battle formation at the city gate. The Arameans of Zobah and Rehob and the men of Tob and Maacah took up a position out in the open fields. When Joab saw that he had two fronts to fight, before and behind, he took his pick of the best of Israel and deployed them to confront the Arameans. The rest of the army he put under the command of Abishai, his brother, and deployed them to confront the Ammonites. Then he said, “If the Arameans are too much for me, you help me. And if the Ammonites prove too much for you, I’ll come and help you. Courage! We’ll fight tooth and nail for our people and for the cities of our God. And GOD will do whatever he sees needs doing!”
