FUEL (Heb. ’ōkhlâh, or ma’ăkhōleth, food). In ancient times, wood, charcoal, various kinds of thorn bushes, dried grass, and the dung of camels and cattle were used as fuel. There is no evidence that coal was used by the Hebrews as fuel; their houses had no chimneys (Isa.9.5, Isa.9.19; Ezek.4.12; Ezek.15.4, Ezek.15.6; Ezek.21.32).
