1 Chronicles 19:7-9

New Catholic Bible

⁷ They hired thirty-two thousand chariots for themselves along with the king of Maacah and his people. They came and camped in front of Medeba. The Ammonites also assembled from out of their cities and went out to fight.

⁸ David heard about this, so he sent Joab and his army of brave warriors out. ⁹ The Ammonites came and arranged themselves in battle line at the gate to the city while the kings who had come with them stood in the fields by themselves.
