Numbers 6:1-4

Again the Lord spoke to Moses, saying, 2 “Say to the sons of Israel, ‘When a man or a woman makes a special vow, the vow of a Nazirite,that is, one separated and dedicated 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==. 4 [a]All the time of his separation he shall not eat anything produced from the grapevine, from the seeds even to the skins.
