Silk is a valuable textile. In the biblical material, the term sometimes represents silk cloth, while in other passages older translations use it where fine linen is intended.
Silk is explicitly mentioned among the luxury goods of the symbolic Babylon in Revelation. Other Old Testament uses of the word “silk” are identified in the supplied material as references to fine linen or possibly damask cloth.
Silk was common in New Testament times. The Hebrew language did not use the well-known classical name for the substance, and the material was probably known through extended commercial relations.
