Numbers 6:1-3

And the LORD spake unto Moses, saying, Speak unto the children of Israel, and say unto them, When either man or woman shall separate {themselves} to vow a vow of a Nazarite, to separate {themselves} unto the LORD: {to separate...: or, to make themselves Nazarites} He shall separate {himself} 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.
