Numbers 6:2-3

MKJV(i) 2 Speak to the sons of Israel, and say to them, When a man or a woman shall vow a vow, a vow of a Nazarite, to be separated to Jehovah, 3 he shall separate from wine and strong drink and shall drink no vinegar of wine, or vinegar of strong drink; neither shall he drink any liquor of grapes, nor eat moist grapes or dried.
