1 Chronicles 19:7-9

New Revised Standard Version Catholic Edition

⁷ They hired thirty-two thousand chariots and the king of Maacah with his army, who came and camped before Medeba. And the Ammonites were mustered from their cities and came to battle. ⁸ When David heard of it, he sent Joab and all the army of the warriors. ⁹ The Ammonites came out and drew up in battle array at the entrance of the city, and the kings who had come were by themselves in the open country.
