Numbers 6:3-5

Douay-Rheims 1899 American Edition

³ They shall abstain from wine, and from every thing that may make a man drunk. They shall not drink vinegar of wine, or of any other drink, nor any thing that is pressed out of the grape: nor shall they eat grapes either fresh or dried.

⁴ All the days that they are consecrated to the Lord by vow: they shall eat nothing that cometh of the vineyard, from the raisin even to the kernel.

⁵ All the time of his separation no razor shall pass over his head, until the day be fulfilled of his consecration to the Lord. He shall be holy, and shall let the hair of his head grow.
