2 Samuel 10:6-14

⁶ When the Ammonites saw that they had become odious to David, the Ammonites sent and hired the Syrians of Beth-re'hob, and the Syrians of Zobah, twenty thousand foot soldiers, and the king of Ma'acah with a thousand men, and the men of Tob, twelve thousand men. ⁷ And when David heard of it, he sent Jo'ab and all the host of the mighty men. ⁸ And the Ammonites came out and drew up in battle array at the entrance of the gate; and the Syrians of Zobah and of Rehob, and the men of Tob and Ma'acah, were by themselves in the open country. ⁹ When Jo'ab saw that the battle was set against him both in front and in the rear, he chose some of the picked men of Israel, and arrayed them against the Syrians; ¹⁰ the rest of his men he put in the charge of Abi'shai his brother, and he arrayed them against the Ammonites. ¹¹ And he said, "If the Syrians are too strong for me, then you shall help me; but if the Ammonites are too strong for you, then I will come and help you. ¹² Be of good courage, and let us play the man for our people, and for the cities of our God; and may the Lord do what seems good to him." ¹³ So Jo'ab and the people who were with him drew near to battle against the Syrians; and they fled before him. ¹⁴ And when the Ammonites saw that the Syrians fled, they likewise fled before Abi'shai, and entered the city. Then Jo'ab returned from fighting against the Ammonites, and came to Jerusalem.
