The LORD said to Moses,
“Speak to the Israelites and say to them: ‘If a man or woman wants to make a special vow, a vow of dedication to the LORD as a Nazirite,
they must abstain from wine and other fermented drink and must not drink vinegar made from wine or other fermented drink. They must not drink grape juice or eat grapes or raisins.
As long as they remain under their Nazirite vow, they must not eat anything that comes from the grapevine, not even the seeds or skins.
