fine linen high quality cloth made from the stems of the flax plant; known for its strength and coolness
1 It would be possible to treat λίνον[a] linen cloth (6.165) and βύσσος fine linen (6.166) as meaning linen garments and fine linen garments respectively. However, there is no need for setting up such a separate meaning for NT usage, especially since in both REV 15:6 and LUK 16:19 the semantic element of garment or clothing is a significant compound of the verb meaning to dress, and thus the referents would naturally be garments. The same applies to πορφύρα (6.169) in LUK 16:19.
