The Nazarites were forbidden to make use of the razor (Num. 6:5; Judg. 13:5). At their consecration the Levites were shaved all over with a razor (Num. 8:7; comp. Ps. 52:2; Ezek. 5:1).

And thou, son of man, take thee a sharp knife, take thee a barber's razor, and cause it to pass upon thine head and upon thy beard: then take thee balances to weigh, and divide the hair.

Besides other usages, the practice of shaving the head after the completion of a vow must have created among the Jews a necessity for the special trade of a barber. (Leviticus 14:8; Numbers 6:9,18; 8:7; Judges 13:5; Isaiah 7:20; Ezekiel 5:1; Acts 18:18) The instruments of his work were probably, as in modern times, the razor, the basin, the mirror, and perhaps also the scissors. See (2 Samuel 14:26) Like the Levites, the Egyptian priests were accustomed to shave their whole bodies.
