Nahash was king of the children of Ammon, as appears from 1Sa 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” 2Sa 17:25; 1Ch 2:16-17; and, perhaps, in consequence of this connection, he and his family were very friendly to David 2Sa 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 Jdg 10:6-18; 11.
