2 Samuel 10:3

And the princes of the children of Ammon said unto Hanun their lord, Thinkest thou that David doth honour thy father, that he hath sent comforters unto thee? hath not David rather sent his servants unto thee, to search the city, and to spy it out, and to overthrow it?

After the death of Nahash, David sent an embassy of sympathy to his son Hanun, and the princes of Ammon answered by turning that kindness into an accusation that his servants had come to explore the city, to spy it out, and to overthrow it. David had sent those comforters out of gratitude for kindness Nahash had shown him while he was a fugitive from Saul. That earlier kindness of Nahash to David had itself been prompted wholly by hostility to Saul, and that same hatred still drove the Ammonites.

They still remembered how Israel had defeated Nahash's cruel demand for the right eyes of the people of Jabesh-gilead and had rescued those he intended to humble and mutilate. Hating the true God and Israel and unable to comprehend David's generous spirit, the counselors misconstrued his message from envy and suspicion, and Hanun accepted their view that the messengers were spies and treated them with scorn and insult. This response exposed the treacherous character of the Ammonites and showed why Israel was not to enter into a league with them. Their envious suspicion illustrates how Satan controls minds to misinterpret even the very best intentions.
