II Samuel 10:6, 8

When the people of Ammon saw that they had made themselves repulsive to David, the people of Ammon sent and hired the Syrians of Beth Rehob and the Syrians of Zoba, twenty thousand foot soldiers; and from the king of Maacah one thousand men, and from Ish-Tob twelve thousand men.

Then the people of Ammon came out and put themselves in battle array at the entrance of the gate. And the Syrians of Zoba, Beth Rehob, Ish-Tob, and Maacah were by themselves in the field.
