6 And Hashem spoke unto Moshe, saying,

² Speak unto the Bnei Yisroel, and say unto them, When either ish or isha shall separate themselves to vow a neder of a Nazir, to separate themselves unto Hashem;

³ He shall separate himself from yayin and shekhar (fermented drink), and shall drink no chometz (vinegar) of yayin, or chometz of shekhar, neither shall he drink any grape juice, nor eat moist grapes, or dried (i.e., raisins).
