(1.) Chald. attun, a large furnace with a wide open mouth, at
the top of which materials were cast in (Dan. 3:22, 23; compare
Jer. 29:22). This furnace would be in constant requisition, for
the Babylonians disposed of their dead by cremation, as did also
the Accadians who invaded Mesopotamia.

(2.) Heb. kibshan, a smelting furnace (Gen. 19:28), also a
lime-kiln (Isa. 33:12; Amos 2:1).

(3.) Heb. kur, a refining furnace (Prov. 17:3; 27:21; Ezek.

(4.) Heb. alil, a crucible; only used in Ps. 12:6.

(5.) Heb. tannur, oven for baking bread (Gen. 15:17; Isa.
31:9; Neh. 3:11). It was a large pot, narrowing towards the top.
When it was heated by a fire made within, the dough was spread
over the heated surface, and thus was baked. "A smoking furnace
and a burning lamp" (Gen. 15:17), the symbol of the presence of
the Almighty, passed between the divided pieces of Abraham's
sacrifice in ratification of the covenant God made with him.
