1 Chronicles 19:1-3

Some time after this, King Nahash of the Ammonites died, and his son Hanun became king. David said, “I am going to show loyalty to Hanun because his father, Nahash, was always loyal to me.” So David sent messengers to express sympathy to Hanun about his father’s death. But when David’s ambassadors arrived in the land of Ammon, the Ammonite commanders said to Hanun, “Do you really think these men are coming here to honor your father? No! David has sent them to spy out the land so they can come in and conquer it!”
