(12) And the Lord spake unto Moses and Aaron.--We read in Psalm 106:33 that the Israelites "provoked (literally, made to rebel) his spirit, so that he spake unadvisedly with his lips." Whatever was the nature of the sin thus committed, it is clear that Aaron was a participator in it with Moses. Some have thought that the sin of Moses consisted in addressing the people as rebels (or as rebellious ones); but this is the charge repeatedly brought against them in the book of Deuteronomy (see Numbers 1:26; Numbers 1:43; Numbers 9:23; Numbers 31:27), under circumstances in which it is impossible to suppose that Moses committed the same sin. It has also been thought that the sin of Moses and Aaron consisted in arrogating to themselves the honour which was due only to God. "Must we fetch you water?" but the personal pronoun does not occur in the Hebrew, as it might, and probably would, have occurred, if intended to be emphatic. The more probable explanation appears to be that, notwithstanding the miraculous supply of water which had begun at Rephidim, and which had been subsequently continued, Moses and Aaron distrusted the word and power (Numbers 20:12) of God, and that they yielded to the impulse of impatience and anger, as betrayed both by the language which they used and by the double smiting of the rock, to which Moses had been commanded only to speak. To what degree Aaron was concerned in these sins can be inferred only from the facts that he, as well as Moses, was charged with the sin of unbelief, and that the punishment of exclusion from the land of Canaan was inflicted upon both.

(12) Therefore ye shall not bring this congregation . . . --In Numbers 14:30 Caleb and Joshua are mentioned as the only exceptions to the general sentence of exclusion pronounced against the generation which had come out of Egypt, and which consisted of those who were above twenty years of age. It does not appear, however, from that passage whether the sentence pronounced against Moses and Aaron had, or had not, been delivered at that time, inasmuch as they were the speakers on that occasion, and they belonged to the tribe of Levi, which was not included in the numbering to which reference is made in Numbers 20:29.

Verse 12. - Because ye believed me not, to sanctify me in the eyes of the children of Israel. It is very important, and at the same time very difficult, to understand what the precise sin of Moses and Aaron was upon this occasion. That it was very serious is manifest from the punishment which is entailed. Aaron, indeed, does not appear in the narrative, save in his usual subordinate position as associated with his brother by the Divine mandate. It has been said that he might have checked the unadvised words of Moses, but that is wholly beside the mark. Aaron had obviously no control whatever over his far more able and energetic brother, and therefore could have no responsibility in that respect. We can only suppose that he inwardly assented to the language and conduct with which he was outwardly associated, and therefore shared the guilt. A less degree of sin was (so to speak) necessary in his cause, because he had on former occasions so greatly dishonoured his office; and the anger of God against the sin of his ministers, although laid to sleep, is ever ready to awake upon the recurrence of a similar provocation. We may therefore dismiss him, and consider only the case of Moses. It is impossible to suppose that Moses actually doubted the power of God to supply the present need, for he held in his hand the very rod with which he had struck the rock in Rephidim, nor is there anything in his words or acts upon this occasion to imply any such disbelief. The language of Numbers 11:21, 22 may be cited on the other side, but that was spoken in passion, and spoken to God, and cannot be held as expressing an actual failure of faith. Nor do subsequent references point to unbelief as having been the sin of Moses (cf. Numbers 27:14; Deuteronomy 32:51; Psalm 106:33). Rather, they point to disobedience and indiscretion; to such disloyal conduct and language as produced a bad impression upon the people, and did not place the Divine character before them in its true light. We must understand, therefore, that the want of belief with which Moses stood charged was not a want of faith in the power of God, but a want of obedience to the will of God, bearing in mind that the two faults of disbelief and disobedience are but two sides of one inward fact, and are perpetually confounded in the language of Scripture (compare the use of ἀπειθεῖν in the New Testament). What then was the disobedience of Moses? Here, again, the more obvious answer is insufficient. It is true that Moses struck the rock twice instead of (or perhaps in addition to) speaking to it; but God had bid him take the rod, and he might naturally think he was meant to use it as before; moreover, the people could not have known anything of the exact terms of the command, and would have thought no more of his striking the rock at Kadesh than at Rephidim; but it was the fact of the bad impression made upon the people which was the ground of the Divine rebuke. We come back, therefore, to the simple conclusion expressed by the Psalmist (Psalm 106:32, 33), that Moses lost his temper, and in the irritation of the moment spoke and acted in such a way and in such a spirit as to dishonour his Master and to impair the good effect of the Divine beneficence. It is quite likely that the repeated striking of the rock was one sign of the anger to which Moses gave way, but we could hardly have attached any serious character to the act if it had stood alone. It is in the words of Moses, words in which he associated Aaron with himself, that we must find the explanation of the displeasure he incurred. That he called the people "rebels" was unseemly, not because it was untrue, or because it was an uncalled-for term of reproach, but because he himself was at that very moment a rebel, and disloyal in heart to his Master (cf. verse 24). That he should say, "Must we fetch you water out of this rock?" showed how completely he was carried away. It is true that God had said to him, "Thou shalt bring forth to them water," and, "Thou shalt give the congregation... drink" (compare this with Exodus 17:6), and it is probable that his own words were more or less consciously dictated by this remembrance; but he knew very well that the Divine mandate afforded him no real justification; that he and Aaron were the merest instruments in the hand of God; that it was peculiarly necessary to keep this fact before the minds of the people; nevertheless, his vexation and anger betrayed him into putting himself - a mere man, and a man too in a very bad temper - into the place of God before the eyes of the whole congregation. Moses had fallen at least once before (see on Numbers 11:11-15) into a similar error, one so natural to an angry mind; but this was the first time that he had made his error public, and thereby dishonoured the Master whom it was his special duty to uphold and glorify. This was the sin, and if the punishment seem disproportionate, it must be remembered that the heinousness of a sin depends quite as much on the position of the sinner as upon its intrinsic enormity. Ye shall not bring this congregation into the land. That they should die in the wilderness was implied in this sentence, but was not strictly a part of the sentence itself. Moses, indeed, although he did not enter the land of promise in its narrower sense, yet he died within the inheritance of Israel. Since they had behaved unworthily of their high office as leaders of the people, therefore that office should be taken from them before the glorious end.

20:1-13 After thirty-eight years' tedious abode in the wilderness, the armies of Israel advanced towards Canaan again. There was no water for the congregation. We live in a wanting world, and wherever we are, must expect to meet with something to put us out. It is a great mercy to have plenty of water, a mercy which, if we found the want of, we should more own the worth of. Hereupon they murmured against Moses and Aaron. They spake the same absurd and brutish language their fathers had done. It made their crime the worse, that they had smarted so long for the discontent and distrusts of their fathers, yet they venture in the same steps. Moses must again, in God's name, command water out of a rock for them; God is as able as ever to supply his people with what is needful for them. But Moses and Aaron acted wrong. They took much of the glory of this work of wonder to themselves; Must we fetch water? As if it were done by some power or worthiness of their own. They were to speak to the rock, but they smote it. Therefore it is charged upon them, that they did not sanctify God, that is, they did not give to him alone that glory of this miracle which was due unto his name. And being provoked by the people, Moses spake unadvisedly with his lips. The same pride of man would still usurp the office of the appointed Mediator; and become to ourselves wisdom, righteousness, and sanctification, and redemption. Such a state of sinful independence, such a rebellion of the soul against its Saviour, the voice of God condemns in every page of the gospel.And the Lord spake unto Moses and Aaron,.... Out of the cloud, where his glory appeared, and still continued:

because ye believed me not, to sanctify me in the eyes of the children of Israel; that Moses and Aaron committed an evil which was displeasing to the Lord is certain, but what that was is variously represented. Some say their sin was, that the order was to speak to the rock, whereas it was smitten, and not spoken to; but why then was Moses bid to take the rod with him, if it was not to smite with it, as he had done before at Horeb? and besides, this would only have been the sin of Moses, and not of Aaron; others think, that what provoked the Lord was, that the Israelites were called "rebels"; but this is a name the Lord himself gave them, Numbers 17:10, and was what they justly deserved; and what after this Moses says of them, which, had this been the case, he would have been careful to have abstained from, Deuteronomy 9:24. Others are of opinion, that what was displeasing to the Lord was, that the bringing the water out of the rock was ascribed to themselves, and not to him; "must we fetch you water", &c. Others suppose the sin was in smiting the rock twice, and in anger; but this could only be the fault of Moses at most. Dr. Lightfoot (b) thinks the particular fault was this, that Moses expressed his displeasure and resentment to the Israelites, that on their murmuring a new rock was opening, which portended a new and long stay in the wilderness, as the opening of the first rock at Horeb did when he and Aaron were in expectation of being soon out of the wilderness, and now they feared they were beginning anew their abode in it; but it is certain from the text that unbelief was their sin; they were diffident about the will of God to bring water out of the rock for such a rebellious people, and they did not put them in mind of the miracles God had wrought in former time, to encourage their faith; and so the Lord was not sanctified by them before the people, as he ought to have been:

therefore ye shall not bring this congregation into the land which I have given them; the land of Canaan, a grant of which was made to their fathers, and particularly to this generation, and into which they would certainly be brought; but not by Moses and Aaron, who were excluded because of their unbelief, and accordingly both died before the entrance of the people into the land. This, according to the Targum of Jonathan, and Jarchi, was said with an oath; see Hebrews 3:18.
