c.1300, from Anglo-French barbour (attested as a surname from early 13c.), from Old French barbeor, barbieor (Modern French barbier, which has a more restricted sense than the English word), from Vulgar Latin *barbatorem, from Latin barba "beard" (see barb (n.)). Originally also regular practitioners of surgery, they were restricted to haircutting and dentistry under Henry VIII.
Found only once, in Ezek. 5:1, where reference is made to the Jewish custom of shaving the head as a sign of mourning. The Nazarites were untouched by the razor from their birth (Num. 6:5). Comp. Judg. 16:19.
