'Razor' in the Bible

"'All the days of his vow of separation no razor shall come on his head, until the days are fulfilled, in which he separates himself to Yahweh. He shall be holy. He shall let the locks of the hair of his head grow long.

You shall do this to them, to cleanse them: sprinkle the water of cleansing on them, let them shave their whole bodies with a razor, and let them wash their clothes, and cleanse themselves.
