Numbers 6:2-4  American Standard Version

² Speak unto the children of Israel, and say unto them, When either man or woman shall make a special vow, the vow of ^[a]a Nazirite, to ^[b]separate himself unto Jehovah, ³ he shall separate himself from wine and strong drink; he shall drink no vinegar of wine, or vinegar of strong drink, neither shall he drink any juice of grapes, nor eat fresh grapes or dried. ⁴ All the days of his ^[c]separation shall he eat nothing that is made of the grape-vine, from the kernels even to the husk.
