Fuel
Easton's Bible Dictionary
Almost every kind of combustible matter was used for fuel, such as the withered stalks of herbs (Matt 6:30), thorns (Ps 58:9; Eccl 7:6), animal excrements (Ezek 4:12-15; 15:4, 6; 21:32). Wood or charcoal is much used still in all the towns of Syria and Egypt. It is largely brought from the region of Hebron to Jerusalem.

fu'-el ('okhlah, or ma'akholeth, "food"): Is mentioned specifically only in the Old Testament, in Isa 9:5; Isa 9:19; Ezek 15:4; Ezek 15:6; Ezek 21:32. Its general, literal meaning in these connections is "food for fire," and might include any sort of combustible material. The common forms of fuel were wood of various sorts (even including thorns, Ps 58:9; Ps 118:12; Eccl 7:6), and dried stalks of flowers or grass (Matt 6:30), charred wood as charcoal (Lev 16:12; Isa 44:19, and frequently), and dried dung (Ezek 4:12; Ezek 4:15). There is no certain indication that our coal was known to the Hebrews as fuel, and their houses, being without chimneys, were not constructed for the extensive use of fuel for warmth.
