wool

The fleece of a sheep, used in ancient Palestine for clothing (Lev 13:47-48; Ezek 34:3). White wool was one of the principal products traded by Damascus to Tyre (Ezek 27:18). The wool of a hundred thousand rams had to be paid by Mesha, king of Moab, as tribute to Ahab, king of Israel (2Kgs 3:4). The color of undyed wool became a symbol of purity (Isa 1:18) and whiteness (Dan 7:9; Rev 1:14).
