Smoking furnace, one of the places where "David himself and his men were wont to haunt" (1 Samuel 30:30, 31). It is probably identical with Ashan (Joshua 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."
