Fuller @ The word "full" is from the Anglo-Saxon fullian, meaning "to whiten." To full is to press or scour cloth in a mill. This art is one of great antiquity. Mention is made of "fuller's soap" Malachi:3:2), and of "the fuller's field" ( 2Kings:18:17). At his transfiguration our Lord's rainment is said to have been white "so as no fuller on earth could white them" Mark:9:3). En-rogel (q.v.), meaning literally "foot-fountain," has been interpreted as the "fuller's fountain," because there the fullers trod the cloth with their feet.
Fuller's field @ a spot near Jerusalem ( 2Kings:18:17; Isaiah:36:2Isaiah:7:3), on the side of the highway west of the city, not far distant from the "upper pool" at the head of the valley of Hinnom. Here the fullers pursued their occupation.
Fuller's soap @ (Heb. borith mekabbeshim, i.e., "alkali of those treading cloth"). Mention is made Proverbs:25:20; Jeremiah:2:22) of nitre and also Malachi:3:2) of soap (Heb. borith) used by the fuller in his operations. Nitre is found in Syria, and vegetable alkali was obtained from the ashes of certain plants. (See SOAP.)
