When the priest was on duty he was to abstain from wine and strong drink, lest he should commit excess (see Leviticus 10:1), and so become disqualified for carrying out the precepts of the ceremonial Law.

Leviticus 10:9

Strong drink - The Hebrew word is employed here to denote strong drinks of any kind except wine made from the grape.

Do not drink wine nor strong drink - The cabalistical commentator, Baal Hatturim, and others, have supposed, from the introduction of this command here, that Aaron's sons had sinned through excess of wine, and that they had attempted to celebrate the Divine service in a state of inebriation. Strong drink - The word שכר shechar, from shachar, to inebriate, signifies any kind of fermented liquors. This is exactly the same prohibition that was given in the case of John Baptist, Luke 1:15 : Οινον και σικερα ου μη πιῃ· Wine and sikera he shall not drink. Any inebriating liquor, says St. Jerome, (Epist. ad nepot)., is called sicera, whether made of corn, apples, honey, dates, or other fruit. One of the four prohibited drinks among the Mohammedans in India is called sakar, (see the Hedaya, vol. iv., p. 158), which signifies inebriating drink in general, but especially date wine or arrack. From the original word probably we have borrowed our term cider or sider, which among us exclusively signifies the fermented juice of apples. See on Luke 1:15 (note).

Do not drink wine or strong drink,.... This law following upon the affair of Nadab and Abihu has caused some to think, and not without some reason, that they were drunk with wine or strong drink, when they offered strange fire; and indeed it is hardly to be accounted for upon any other foot that they should do it; but having feasted that day upon the peace offerings, and drank freely, it being the first day of their entrance on their office, they were, it may be supposed, elated and merry, and drank more than they should; wherefore this law was given, to restrain from such a disorderly and scandalous practice; not only wine, which is inebriating, but strong drink also is forbidden, which, as Aben Ezra says, is made either of a sort of wheat, or honey, or dates: and so Kimchi (p) and Ben Melech on the place after him observe, that this includes whatsoever inebriates, besides wine; and that their doctors say, whosoever drinks milk or honey (they must mean some strong liquor extracted from thence), if he enters into the tabernacle he is guilty:

thou nor thy sons with thee; the Targum of Jonathan adds, as did thy sons, who died by the burning of fire; that is, he and his sons were to avoid drinking wine or strong drink to excess, as his two sons had done, which led them to offer strange fire, for which they suffered death:

when ye go into the tabernacle of the congregation, lest ye die; they might drink wine at other times, in a moderate manner; but it seems by this they were not to drink any at all when they were about to go to service, or to enter into the tabernacle in order to do it: indeed, according to the Jewish canons, every priest that is fit for service, if he drinks wine, it is forbidden him to enter in (to the tabernacle, and so) from the altar (of burnt offering) and inward (into the holy place); and if he goes in and does his service it is profane (unlawful and rejected), and he is guilty of death by the hand of heaven; and he that drinks the fourth part (of a log) of wine at one time, of wine forty days old; but if he drinks less than a fourth part of wine, or drinks a fourth part and stops between, and mixes it with water, or drinks wine out of the press within forty days (i.e. not quite so many days old), though more than a fourth part, he is free, and does not profane his service; if he drinks more than a fourth part of wine, though it is mixed, and though he stops and drinks little by little, he is guilty of death, and his service is profane (or rejected); if he is drunk with the rest of liquors that make drunk, he is forbidden to go into the sanctuary; but if he goes in and serves, and he is drunk with the rest of liquors that make drunk, whether of milk or of figs (a strong liquor made of them), he is to be beaten, but his service is right; for they are not guilty of death but on account of wine in the hour of service; and it does not profane service, but being drunken with wine (q): in imitation of this, Heathen priests were forbid wine, and abstained from it, particularly the Egyptian priests; at whom it is said (r), some of them never drink any wine, and others taste but a little of it, because it is said to harm the nerves, to fill the head, or make it heavy, to hinder invention and excite to lust:

it shall be a statute for ever throughout all your generations: even to the coming of the Messiah; and now under the Gospel dispensation, though wine in moderation is allowed Gospel ministers, yet they are not to be given to it; it is a shame to any Christian man to be drunk with wine, and more especially a minister, and still more so when in his service; see Ezekiel 44:21.

(p) Sepher Shorashim, Rad. (q) Maimon. Hilchot Biath Hamikdash, c. 1. sect. 1. 2. (r) Chaeremon apud Porphyr. de Abstinentia, l. 4. c. 6.

Do not drink wine nor strong drink, thou, nor thy sons with thee, when ye go into the tabernacle of the congregation, lest ye die: it shall be a statute for ever throughout your generations:

10:9 Drink not wine - it is not improbable, that the sin of Nadab and Abihu was owing to this very thing. But if not, yet drunkenness is so odious a sin in itself, especially in a minister, and most of all in the time of his administration of sacred things, that God saw fit to prevent all occasions of it. And hence the devil, who is God's ape, required this abstinence from his priests in their idolatrous service.

10:8-11 Do not drink wine or strong drink. During the time they ministered, the priests were forbidden it. It is required of gospel ministers, that they be not given to wine, 1Ti 3:3. It is, Lest ye die; die when ye are in drink. The danger of death, to which we are continually exposed, should engage all to be sober.
