2 Samuel 10:1-2
1-2Sometime after this, the king of the Ammonites died and Hanun, his son, succeeded him as king. David said, "I'd like to show some kindness to Hanun, the son of Nahash—treat him as well and as kindly as his father treated me." So David sent Hanun condolences regarding his father.
2-3But when David's servants got to the land of the Ammonites, the Ammonite leaders warned Hanun, their head delegate, "Do you for a minute suppose that David is honoring your father by sending you comforters? Don't you think it's because he wants to snoop around the city and size it up that David has sent his emissaries to you?"
