Charles Ellicott Commentary Isaiah 19:9

"Moreover they that work in combed flax, and they that weave white cloth, shall be confounded." — Isaiah 19:9 (ASV)

Moreover they that work in fine flax. —Another class also would find its occupation gone. The “fine flax” was used especially for the dress of the priests (Herod. ii. 81), and for the mummy clothes of the dead (1 Kings 10:28; Ezekiel 27:7).

They that weave networks. —Better, white cloths, the cotton or byssus fabrics for which Egypt was famous.
