Nahash was king of the children of Ammon, as appears from 1 Samuel 12:12. He seems to have been connected with the family of David, since Abigail, David’s sister, was “the daughter (perhaps granddaughter) of Nahash” 2 Samuel 17:25; 1 Chronicles 2:16-17; and, perhaps, in consequence of this connection, he and his family were very friendly to David 2 Samuel 17:27.
Jabesh-Gilead must have been re-populated after its destruction (see marginal reference). The Ammonites and Moabites resented the possession of Gilead by the Israelites Judges 10:6-18; Judges 11.
