And for this prohibition the reason is given (vv. 10, 11): "That ye may put difference between the holy and the common, and between the unclean and the clean; and that ye may teach the children of Israel all the statutes which the Lord hath spoken unto them by the hand of Moses."
It was not then that the use of wine was in itself sinful; for this is taught nowhere in the Old or New Testament, and as a doctrine of religion is characteristic, not of Judaism or Christianity, but only of Mohammedanism, of Buddhism and other heathen religions. The ground of this command of abstinence, as of the New Testament counsel (Rom. xiv. 20, 21), is that of expediency. Because, in the use of wine or strong drink, there was involved a certain risk, that by undue indulgence the judgment might be confused or the memory weakened, so that something might be done amiss; therefore the priests, who were specially commissioned to teach the statutes of the Lord to Israel, and this most of all, by their own carefulness to obey all the least of His commandments, are here warned to abstain whenever about engaging in their official duties. As suggested above, it is at least very natural to infer, from the historical setting of this prohibition, that the fatal offence of Nadab and Abihu was occasioned by such an indulgence in wine or strong drink as made it possible for impulse to get the better of knowledge and judgment.
But, however this may be, the lesson for us abides the same; a lesson which each one according to his circumstances must faithfully apply to his own case. For the Christian it is not enough that he shall abstain from what is in its own nature always sinful; it must be the law of our life that we abstain also from whatever may needlessly become occasion of sin. In this we cannot, indeed, lay down a universal code of law. Heathen reformers have done this, and their imitators in the Church, but never Christ or His Apostles. And this with reason. For that which for one carries with it inevitable risk of sin, is not always fraught with the same danger to another person with a different temperament, or even to the same person under different circumstances. In each instance we must judge for ourselves, taking heed not to abuse our liberty to another's harm; and also, on the other hand, being careful how we judge others in regard to things which in their essential nature are neither right nor wrong. But we shall be wise to recognise the fact that it is just in such things that many Christians do most harm, both to their own souls and to those of others. And in regard to the drinking of wine in particular, one must be blind indeed not to perceive it to be the fact that, whatever the reason may be, the English-speaking peoples seem to be peculiarly susceptible to the danger of undue indulgence in wine and strong drink. On both sides of the Atlantic, drunkenness must be set down as one of the most prevalent national sins.
In deciding the question of personal duty in this and like cases, all believers are bound, as the Lord's priestly people, to remember that He has appointed them that they should walk before Him as a separated people, who, by their daily walk, above all, are to teach others to "put a difference between holy and common, and unclean and clean, and to observe all the statutes which the Lord hath spoken."
In vv. 12-15 we have a repetition of the commandments previously given, concerning the use to be made of the meal-offering and the peace-offering. From this it appears that Moses himself, in view of the tragic occurrence of the day, was stirred up to charge Aaron and his sons anew on matters on which he had already commanded them. And with this intensified care on his part is evidently connected the incident recorded in the verses which follow, where we read that, having repeated the directions as to the meal-offering and the peace-offering (vv. 16, 17), "Moses diligently sought the goat of the sin offering, and, behold, it was burnt; and he was angry with Eleazar and with Ithamar, the sons of Aaron that were left, saying, Wherefore have ye not eaten the sin offering in the place of the sanctuary, seeing it is most holy, and He hath given it you to bear the iniquity of the congregation, to make atonement for them before the Lord?"
It had indeed been commanded, in the case of those sin-offerings of which the blood was brought into the holy place, that their flesh should not be eaten; but that the flesh of all others should be eaten, as belonging to the class of things "most holy," by the priests alone within the Holy Place. Hence Moses continued (ver. 18): "Behold, the blood of it was not brought into the sanctuary within: ye should certainly have eaten it in the sanctuary, as I commanded."
What had been done, as it appears, had been done with Aaron's knowledge and sanction; for Aaron then answered in behalf of his sons (ver. 19): "Behold, this day have they offered their sin offering and their burnt offering before the Lord; and there have befallen me such things as these: and if I had eaten the sin offering to-day, would it have been well-pleasing in the sight of the Lord?"
Of which answer, the intention seems to have been this. In this day of special exaltation and privilege, when for the first time they had performed their solemn priestly duties, when most of all there should have been the utmost care to please the Lord in the very smallest things, His holy Name had been profaned by the will-worship of his sons, and the wrath of God had broken out against them, and, in them, against their father's house. Could it be the will of God that a house in which was found the guilt of such a sin, should yet partake of the most holy things of God in the sanctuary?
From this it appears that the judgment sent into the house of Aaron had had a most wholesome spiritual effect. They had received such an impression of their own profound sinfulness as they had never had before. And it is very instructive to observe that they assume to themselves a part in the sinfulness which had been shown in the sin of Nadab and Abihu. It did not occur to Aaron or his remaining sons to say, in the spirit of Israel in the day of our Lord, "If we had been in their place, we would not have done so." Rather their consciences had been so awakened to the holiness of God and their own inborn evil, that they coupled themselves with the others as under the displeasure of God. Was it possible, even though they personally had not sinned, that such as they should eat that which was most holy unto God? They had thus in the letter disobeyed the law; but because their offence was begotten of a misapprehension, and only showed how deeply and thoroughly they had taken to heart the lesson of the sore judgment, we read that "when Moses heard" their explanation, "it was well pleasing in his sight."
All this which followed the sin of Nadab and Abihu, and the judgment which fell on them, and thus upon the whole house of Aaron, is a most instructive illustration of the working of the chastising judgments of the Lord, when rightly received. Its effect was to awaken the utmost solicitude that nothing else might be found about the tabernacle service, even through oversight, which was not according to the mind of God; and, in those immediately stricken, to produce a very profound sense of personal sinfulness and unworthiness before God. The New Testament gives us a graphic description of this effect of the chastisement of God on the believer, in the account which we have of the result of the discipline which the Apostle Paul inflicted on the sinning member of the Church of Corinth; concerning which he afterward wrote to them (2 Cor. vii. 11): "Behold, this selfsame thing, that ye were made sorry after a godly sort, what earnest care it wrought in you, yea, what clearing of yourselves, yea, what indignation, yea, what fear, yea, what longing, yea, what zeal, yea, what avenging!"
