2 Samuel 10:6-8

6And when the children of Ammon saw that they stank before David, the children of Ammon sent and hired the Syrians of Beth–rehob, and the Syrians of Zoba, twenty thousand footmen, and of king Maacah a thousand men, and of Ish–tob twelve thousand men.1 7And when David heard of it, he sent Joab, and all the army of the mighty men. 8And the children of Ammon came out, and put the battle in array at the entering in of the gate: and the Syrians of Zoba, and of Rehob, and Ish–tob, and Maacah, were by themselves in the field.
