Fuller

 
The word kabas simply implies “to wash,” as it is often translated, and would include “bleaching.” The coming of the Lord is compared to a “refiner's fire, and like fullers' soap,” when the dross and dirt will be cleared away (Mal. 3:22But who may abide the day of his coming? and who shall stand when he appeareth? for he is like a refiner's fire, and like fullers' soap: (Malachi 3:2)). At the transfiguration the clothing of the Lord became so white that it exceeded the whiteness produced by any fuller on earth (Mark 9:33And his raiment became shining, exceeding white as snow; so as no fuller on earth can white them. (Mark 9:3)). It was a reflection of heavenly glory.
