2 Samuel 10:7

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

When they told David this, he sent to meet them, for the men were greatly ashamed. The king said, “Wait at Jericho until your beards have grown, and then return.”

When the children of Ammon saw that they had become odious to David, the children of Ammon sent and hired the Syrians of Beth Rehob and the Syrians of Zobah, twenty thousand footmen, and the king of Maacah with one thousand men, and the men of Tob twelve thousand men.

The children of Ammon came out, and put the battle in array at the entrance of the gate. The Syrians of Zobah and of Rehob and the men of Tob and Maacah were by themselves in the field.

Now when Joab saw that the battle was set against him before and behind, he chose of all the choice men of Israel and put them in array against the Syrians.

The rest of the people he committed into the hand of Abishai his brother; and he put them in array against the children of Ammon.
