1 Chronicles 19:2-4

New Century Version

² David said, “Nahash was loyal to me, so I will be loyal to his son Hanun.” So David sent messengers to comfort Hanun about his father’s death.

David’s officers went to the land of the Ammonites to comfort Hanun. ³ But the Ammonite leaders said to Hanun, “Do you think David wants to honor your father by sending men to comfort you? No! David sent them to study the land and capture it and spy it out.” ⁴ So Hanun arrested David’s officers. To shame them he shaved their beards and cut off their clothes at the hips. Then he sent them away.
