This noun simply means wool, the fiber from sheep. In Hebrews 9:19, Moses sprinkled the scroll and people with blood using scarlet wool and hyssop—ritual implements for purification. In Revelation 1:14, the glorified Christ's head and hair are described as 'white like white wool'—brilliant, pure whiteness. The multilingual evidence is uniform: Spanish 'lana', French and German 'Wolle'—all meaning wool. Classical usage described wool in various contexts: greasy unwashed wool, dyed wool, wool for weaving. The biblical uses are metaphorical (Revelation's whiteness) or ritual (Hebrews' purification rite).
