King Hanun the son of Nahash
After his father Nahash died, Hanun reigned after him. (2 Samuel 10:1)
David sent servants to console him concerning his father, but the princes of the Ammonites told him, "Do you think, because David has sent comforters to you, that he is honoring your father? Has not David sent his servants to you to search the city and to spy it out and to overthrow it?" So Hanun took David's servants and shaved off half the beard of each and cut off his garment in the middle, at his hips, then sent them all away.
The Ammonites made themselves a stench to David. The Ammonites, Syrians of Beth-rehob and Zobah, 20,000 foot soldiers, men of Maacah, 1,000 men, and men of Tob, 12,000 men, drew up against David at the gate and fled before Joab and Abishai. Hadadezer sent out Syrians from beyond the Euphrates, but they fled and were defeated by King David. All kings who were servants to Hadadezer made peace with Israel, and the Syrians were afraid to save the Ammonites anymore.
