1 Chronicles 19:1-2

1After some time, Nahash, the king of the Ammonites, died. His son became the new king.

2David thought, ‘Nahash was kind to me, so I will be kind to his son Hanun.’ So David sent some of his officers to give a message to Hanun. David wanted to tell Hanun that he was sorry that his father Nahash had died. David's officers took his kind message to the land of the Ammonites.
