2 Samuel 10:1-6

When Nahash king of the Ammonites died, his son Hanun became king after him. David said, “Nahash was loyal to me, so I will be loyal to his son Hanun.” So David sent his messengers to comfort Hanun about his father’s death. David’s officers went to the land of the Ammonites. But the Ammonite leaders said to Hanun, their master, “Do you think David wants to honor your father by sending men to comfort you? No! David sent them to study the city and spy it out and capture it!” So Hanun arrested David’s officers. To shame them he shaved off half their beards and cut off their clothes at the hips. Then he sent them away. When the people told David, he sent messengers to meet his officers because they were very ashamed. King David said, “Stay in Jericho until your beards have grown back. Then come home.” The Ammonites knew that they had insulted David. So they hired twenty thousand Aramean foot soldiers from Beth Rehob and Zobah. They also hired the king of Maacah with a thousand men and twelve thousand men from Tob.
