Numbers 6:3

3 they shall abstain from wine, and from all thing that may make drunken; they shall not drink vinegar of wine, and of anything able to make drunken, and whatever thing is pressed out of the grape; they shall not eat fresh grapes and dry, (they shall abstain from wine, and from all things that can make them drunk; they shall not drink wine vinegar, or any other thing that is able to make them drunk, or whatever is pressed out of the grape; they shall not eat fresh grapes, or dried grapes,)

Numbers 6:3 Meaning and Commentary

Numbers 6:3

He shall separate [himself] from wine
Old or new, as Ben Gersom; from drinking it, any of it: not only from an immoderate and excessive drinking of it, which every man should abstain from, but from drinking of it at all, that he might be more free and fit for the service of God; for prayer, meditation, reading the Scriptures, and attendance on the worship of God in all its branches, and be less liable to temptations to sin; for, as Aben Ezra observes, many transgressions are occasioned by wine, which, if drank immoderately, intoxicates the mind, and unfits for religious duties, excites lust, and leads on to many vices:

and strong drink;
any other intoxicating and inebriating liquor besides wine, or any other sort of wines besides such that is made of the fruit of the vine, as wines of pomegranates, dates or such as are made of barley, as our ale, or of apples and pears, called cider and perry, respectively:

and shall drink no vinegar of wine, or vinegar of strong drink;
all the three Targums paraphrase it, vinegar of new wine, and vinegar of old wine, these operating in like manner as wine and strong drink themselves:

neither shall he drink any liquor of grapes;
any liquor in which grapes are macerated, as the Targum of Jonathan; or water into which they are squeezed, or which is made of the lees of wine, or is a second sort of wine made of the grapes after they have been pressed, which we call "tiff":

nor eat moist grapes or dried;
which have somewhat of the nature and taste of wine, and produce some of the like effects, and may lead to a desire after drinking it; wherefore this, as other things mentioned, are, as Aben Ezra says, a kind of an hedge, to keep at a distance from drinking wine.

Numbers 6:3 In-Context

1 And the Lord spake to Moses, and said,

2 Speak thou to the sons of Israel, and thou shalt say to them, When a man either a woman maketh a vow, that they be hallowed, and they will hallow themselves to the Lord, (Say thou to the Israelites, When a man or a woman maketh a vow, that they will become a Nazarite, and they will consecrate, or will dedicate, themselves to the Lord,)

3 they shall abstain from wine, and from all thing that may make drunken; they shall not drink vinegar of wine, and of anything able to make drunken, and whatever thing is pressed out of the grape; they shall not eat fresh grapes and dry, (they shall abstain from wine, and from all things that can make them drunk; they shall not drink wine vinegar, or any other thing that is able to make them drunk, or whatever is pressed out of the grape; they shall not eat fresh grapes, or dried grapes,)

4 all [the] days in which they be hallowed by a vow to the Lord; they shall not eat whatever thing may be of the vinery, from the rind till to the little grains that be in the midst of the grape.

5 All the time of his separating, or of his avow holding, a razor shall not pass upon his head, unto the day(s) be fulfilled in which he is hallowed to the Lord; he shall be holy, and the hair of his head shall wax. (All the time of his separation, or of the keeping of his vow, a razor shall not pass over his head, until the days be fulfilled in which he is consecrated, or is dedicated, to the Lord; he shall be holy, and his head hair shall grow.)
