Chor-ashan

smoking furnace, one of the places where "David himself and his men were wont to haunt" (1Sam 30:30 ; 30:31). It is probably identical with Ashan (Josh 15:42; 19:7), a Simeonite city in the Negeb, i.e., the south, belonging to Judah. The word ought, according to another reading, to be "Bor-ashan."
