1 Chronicles 19:6-15

⁶ And the children of Ammon saw that they had made themselves odious to David; and Hanun and the children of Ammon sent a thousand talents of silver to hire them chariots and horsemen out of Mesopotamia, and from the Syrians of Maacah, and from Zobah. ⁷ And they hired thirty-two thousand chariots, and the king of Maacah and his people; and they came and encamped before Medeba. And the children of Ammon gathered together from their cities, and came to battle. ⁸ And David heard [of it], and he sent Joab, and all the host, the mighty men. ⁹ And the children of Ammon came out, and put the battle in array at the entrance of the city; and the kings that had come were by themselves on the field. ¹⁰ And Joab saw that the front of the battle was against him before and behind; and he chose out of all the choice men of Israel, and put them in array against the Syrians; ¹¹ and the rest of the people he gave into the hand of Abishai his brother, and they set themselves in array against the children of Ammon. ¹² And he said, If the Syrians be too strong for me, then thou shalt help me; and if the children of Ammon be too strong for thee, then I will help thee. ¹³ Be strong, and let us shew ourselves valiant for our people, and for the cities of our God; and Jehovah will do what is good in his sight. ¹⁴ And Joab and the people that were with him drew near in front of the Syrians to the battle; and they fled before him. ¹⁵ And when the children of Ammon saw that the Syrians fled, they likewise fled before Abishai his brother, and entered into the city. And Joab came to Jerusalem.
