'Linen' in the Bible

The sons of Shelah son of Judah: Er the father of Lecah and Laadah the father of Mareshah, and the families of the house of the linen workers at Beth-ashbea;

David was clothed with a robe of fine linen, as were all the Levites who carried the ark, and the singers and Chenaniah, director of the music of the singers. David also wore an ephod (a priestly upper garment) of linen.
