2 "Speak to the sons of Israel and say to them, 'When a man or woman makes a special vow, the vow of a Nazirite, to dedicate himself to the LORD ,

3 he shall abstain from wine and strong drink; he shall drink no vinegar, whether made from wine or strong drink, nor shall he drink any grape juice nor eat fresh or dried grapes.
