Hastings' Dictionary of the Bible (1898)
RA'ZOR. The usage of shaving the head after completing a vow must have established the barber's trade quite early among the Hebrews. The instruments used were exactly the same as in our days - the razor, the scissors, the basin, and the mirror. Razors are mentioned in Num 6:5; Jud 13:5; 1 Kgs 16:17; 1 Sam 1:11; Eze 5:1, and figuratively in Ps 52:2; Isa 7:20. See Hair.
