HANUN

from Easton's 1897 Bible Dictionary
Hanun
graciously given. (1.) The son and successor of Nahash, king of
Moab. David's messengers, sent on an embassy of condolence to
him to Rabbah Ammon, his capital, were so grossly insulted that
he proclaimed war against Hanun. David's army, under the command
of Joab, forthwith crossed the Jordan, and gained a complete
victory over the Moabites and their allies (2 Sam. 10:1-14) at
Medeba (q.v.).

  (2.) Neh. 3:13. (3.) 3:30.
