Parashat Chukat/Balak - HJC 2020 Hitting the Rock: Why was Moses harshly punished for such a minor infraction?

The Israelites arrived in a body at the wilderness of Zin on the first new moon, and the people stayed at Kadesh. Miriam died there and was buried there. The community was without water, and they joined against Moses and Aaron. The people quarreled with Moses, saying, “If only we had perished when our brothers perished at the instance of the LORD! Why have you brought the LORD’s congregation into this wilderness for us and our beasts to die there? Why did you make us leave Egypt to bring us to this wretched place, a place with no grain or figs or vines or pomegranates? There is not even water to drink!” Moses and Aaron came away from the congregation to the entrance of the Tent of Meeting, and fell on their faces. The Presence of the LORD appeared to them, and the LORD spoke to Moses, saying, “You and your brother Aaron take the rod and assemble the community, and before their very eyes order the rock to yield its water. Thus you shall produce water for them from the rock and provide drink for the congregation and their beasts.” Moses took the rod from before the LORD, as He had commanded him. Moses and Aaron assembled the congregation in front of the rock; and he said to them, “Listen, you rebels, shall we get water for you out of this rock?” And Moses raised his hand and struck the rock twice with his rod. Out came copious water, and the community and their beasts drank. But the LORD said to Moses and Aaron, “Because you did not trust Me enough to affirm My sanctity in the sight of the Israelite people, therefore you shall not lead this congregation into the land that I have given them.” Those are the Waters of Meribah—meaning that the Israelites quarrelled with the LORD—through which He affirmed His sanctity.

יען לא האמנתם בי BECAUSE YE BELIEVED ME NOT — Scripture discloses the fact that but for this sin alone, they would have entered the land of Canaan, in order that people should not say of them, “Even as the sin of the generation of the Wilderness (a term used of those who left Egypt) on whom it was decreed that they should not enter the Land was the sin of Moses and Aaron” (cf. Rashi on Numbers 27:13). But was not the doubting question (cf. Rashi on Numbers 11:22), “shall the sheep and oxen be slaughtered for them?” a more grievous lack of faith in God than this? But because that had been said in private (no Israelites being present and therefore it could have no evil influence upon them), Scripture (God) spared him (and did not make his lack of faith public by pronouncing punishment for it), but here, where all Israel were standing by, Scripture does not spare him because of the Hallowing of the Divine Name (cf. Midrash Tanchuma, Chukat 10).

להקדישני TO SANCTIFY ME — For had you spoken to the rock and it had brought forth water I would have been sanctified before the whole congregation, for they would have said: What is the case with this rock which cannot speak and cannot hear and needs no maintenance? It fulfils the bidding of the Omnipresent God! How much more should we do so?

יען לא האמנתם בי, the sin consisted in their saying: המן הסלע הזה נוציא לכם מים?, “Are we to extract water for you from this rock?” They should have said instead: יוציא ה' לכם מים, “G’d will extract water for you.” (verse 10). In Exodus 16,8 Moses had been careful to phrase the announcement of the forthcoming phenomenon of manna by attributing it to coming directly from G’d. Similarly, when predicting any of the other miracles which had been announce beforehand, Moses had carefully attributed the miracle to G’d. By failing to do so this time they left the way open for some of the people to think that the water when it would gush forth would be the result of Moses’ and Aaron’s combined knowledge.
This is also the meaning of the words (Moses quoting G’d) לא קדשתם אותי, “you have not sanctified Me” (Deuteronomy 32,51). On the first occasion, almost 40 years earlier, when water would be produced from a rock, (Exodus 17,6) G’d had introduced the miracle by announcing: “Here I will be standing there before you on the rock at Chorev. Strike the rock and water will issue from it and the people will drink. And Moses did so in the sight of the elders of Israel.” The seventy elders had observed the cloud of glory moving to above the site of that rock so that the miracle became a public spectacle, lending additional greatness to G’d’s name as the provider. In this instance the people did not observe any evidence of G’d’s involvement so that it was easy to conclude, based on Moses’ and Aaron’s phrasing it, that they themselves had initiated this phenomenon.

לכן לא תביאו, “therefore you will not bring, etc.” Whenever the expression לכן, appears, it indicates that the speaker is saying something in the nature of an oath. Compare: Samuel I 3,14: לכן נשבעתי לבית עלי, “therefore I have sworn concerning the house of Eli;” compare also Deuteronomy 4,21: וישבע לבלתי עברי, “therefore He swore that I may not cross, etc.”

If you were to query that we read at the end of Exodus 6,1 that Rashi explains the words: עתה תראה, “now you will see,” that Moses, while witnessing the Exodus from Egypt, will not witness the crossing of the Jordan into the land of Canaan, (as a penalty for having questioned G-d’s handling of the Israelites since his appointment as their leader) he had already forfeited the right to cross into the land of Israel 40 years earlier, so what is new about G-d’s oath here? We may answer that both incidents combined to deny him entry to the Holy land; [alternately, in Exodus, the matter had only been hinted at, (thus preventing Moses from apologizing and doing teshuvah) and had not been confirmed by G-d with an oath thus making it irrevocable. Ed.].

You make mistakes when you're angry...

Moses' mistake was that, as was mentioned earlier, he felt pressured to hit the rock. However, his true mistake was that it came out of his anger against Israel as he said "Listen, you rebels!" And the moment that anger came upon him, God's presence disappeared.

You didn't believe in me to sanctify me so I won't bring you

...Before the people entered the Land, God wanted to instruct them on the power of evil words, and the power of good words so they will take this lesson with them and so they will not learn to fill their tongues with lies and gossip
