Numbers 6:3

6:3 he must separate ¹  himself from wine and strong drink, he must drink neither vinegar ²  made from wine nor vinegar made from strong drink, nor may he drink any juice ³  of grapes, nor eat fresh grapes or raisins. ⁴ 

Numbers 18:11

18:11 “And this is yours: the raised offering of their gift, along with all the wave offerings of the Israelites. I have given them to you and to your sons and daughters with you as a perpetual ordinance. Everyone who is ceremonially clean in your household may eat of it.

[6:3]  ¹ tn The operative verb now will be the Hiphil of נָזַר (nazar); the consecration to the Lord meant separation from certain things in the world. The first will be wine and strong drink – barley beer (from Akkadian sikaru, a fermented beer). But the second word may be somewhat wider in its application than beer. The Nazirite, then, was to avoid all intoxicants as a sign of his commitment to the Lord. The restriction may have proved a hardship in the daily diet of the one taking the vow, but it spoke a protest to the corrupt religious and social world that used alcohol to excess.

[6:3]  ² tn The “vinegar” (חֹמֶץ, homets) is some kind of drink preparation that has been allowed to go sour.

[6:3]  ³ tn This word occurs only here. It may come from the word “to water, to be moist,” and so refer to juice.

[6:3]  ⁴ tn Heb “dried” (so KJV, ASV, NRSV).
