The art of dyeing is one of great antiquity, although no special mention is made of it in the Old Testament. The Hebrews probably learned it from the Egyptians (see Ex. 26:1; 28:5-8), who brought it to great perfection. In New Testament times Thyatira was famed for its dyers (Acts 16:14). (See COLOUR.)
