'Yarn' in the Bible

"And you will make the robe of the ephod totally of blue [yarn].

And every woman [who was] skilled of heart with her hands they spun, and they brought yarn--the blue and the purple, the crimson and the fine linen.

And he made the robe of the ephod, weaver's work, totally of blue [yarn].

Edom [was] trading [with] you because of the abundance of your products, [trading] with malachite, purple wool yarn and colorful weaving, and fine white fabric and black corals and rubies; [all these] they exchange for your merchandise.
