The materials of which cord was made varied according to the strength required; the strongest rope was probably made of strips of camel hide, as still used by the Bedouins. The finer sorts were made of flax, (Isaiah 19:9) and probably of reeds and rushes. In the New Testament the term is applied to the whip which our Saviour made, (John 2:15) and to the ropes of a ship. (Acts 27:32)
