2 Samuel 10:4-8

Wherefore Hanun took David’s servants, and shaved off the one half of their beards, and cut off their garments in the middle, even to their buttocks, and sent them away.

When they told it unto David, he sent to meet them, because the men were greatly ashamed: and the king said, Tarry at Jericho until your beards be grown, and then return.

And 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.

And when David heard of it, he sent Joab, and all the host of the mighty men.

And 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.
