(א) ולא היה מים לעדה. מִכָּאן שֶׁכָּל אַרְבָּעִים שָׁנָה הָיָה לָהֶם הַבְּאֵר בִּזְכוּת מִרְיָם (תענית ט'):
(1) ולא היה מים לעדה AND THERE WAS NO WATER FOR THE CONGREGATION — Since this statement follows immediately after the mention of Miriam’s death, we may learn from it that during the entire forty years they had the “well” through Miriam’s merit (Taanit 9a).
מֵיתִיבִי רַבִּי יוֹסֵי בְּרַבִּי יְהוּדָה אוֹמֵר שְׁלֹשָׁה פַּרְנָסִים טוֹבִים עָמְדוּ לְיִשְׂרָאֵל אֵלּוּ הֵן מֹשֶׁה וְאַהֲרֹן וּמִרְיָם וְשָׁלֹשׁ מַתָּנוֹת טוֹבוֹת נִיתְּנוּ עַל יָדָם וְאֵלּוּ הֵן בְּאֵר וְעָנָן וּמָן בְּאֵר בִּזְכוּת מִרְיָם עַמּוּד עָנָן בִּזְכוּת אַהֲרֹן מָן בִּזְכוּת מֹשֶׁה מֵתָה מִרְיָם נִסְתַּלֵּק הַבְּאֵר שֶׁנֶּאֱמַר וַתָּמׇת שָׁם מִרְיָם וּכְתִיב בָּתְרֵיהּ וְלֹא הָיָה מַיִם לָעֵדָה וְחָזְרָה בִּזְכוּת שְׁנֵיהֶן
The Gemara raises an objection from a baraita: Rabbi Yosei, son of Rabbi Yehuda, says: Three good sustainers rose up for the Jewish people during the exodus from Egypt, and they are: Moses, Aaron and Miriam. And three good gifts were given from Heaven through their agency, and these are they: The well of water, the pillar of cloud, and the manna. He elaborates: The well was given to the Jewish people in the merit of Miriam; the pillar of cloud was in the merit of Aaron; and the manna in the merit of Moses. When Miriam died the well disappeared, as it is stated: “And Miriam died there” (Numbers 20:1), and it says thereafter in the next verse: “And there was no water for the congregation” (Numbers 20:2). But the well returned in the merit of both Moses and Aaron.

(3) The people quarreled with Moses, saying, “If only we had perished when our brothers perished at the instance of the LORD!
(יז) נְעִבַּר כְּעַן בְּאַרְעָךְ לָא נְעִבַּר בַּחֲקַל וּבִכְרַם וְלָא נִשְׁתֵּי מֵי גוֹב בְּאֹרַח מַלְכָּא נֵזֵל לָא נִסְטֵי לְיַמִּינָא וְלִשְׂמָאלָא עַד דִּנְעִבַּר תְּחוּמָךְ:
(א) נעברה נא בארצך. אֵין לְךָ לְעוֹרֵר עַל הַיְרֻשָּׁה שֶׁל אֶרֶץ יִשְׂרָאֵל, כְּשֵׁם שֶׁלֹּא פָרַעְתָּ הַחוֹב, עֲשֵׂה לָנוּ עֵזֶר מְעַט לַעֲבֹר דֶּרֶךְ אַרְצְךָ: (ב) ולא נשתה מי באר. מֵי בוֹרוֹת הָיָה צָרִיךְ לוֹמַר, אֶלָּא כָּךְ אָמַר מֹשֶׁה, אַעַ"פִּ שֶׁיֵּשׁ בְּיָדֵנוּ מָן לֶאֱכֹל וּבְאֵר לִשְׁתּוֹת, לֹא נִשְׁתֶּה מִמֶּנּוּ, אֶלָּא נִקְנֶה מִכֶּם אֹכֶל וּמַיִם לַהֲנָאַתְכֶם, מִכָּאן לְאַכְסְנַאי אַעַ"פִּ שֶׁיֵּשׁ בְּיָדוֹ לֶאֱכֹל יִקְנֶה מִן הַחֶנְוָנִי, כְּדֵי לְהַנּוֹת אֶת אֻשְׁפִּיזוֹ (תנחומא): (ג) דרך המלך נלך וגו'. אָנוּ חוֹסְמִים אֶת בְּהֶמְתֵּנוּ וְלֹא יִטּוּ לְכָאן וּלְכָאן לֶאֱכֹל (שם):
(1) נעברה נא בארצך LET US PASS, I PRAY THEE, THROUGH THY COUNTRY — You have no right to lay claim to the land of Israel as an inheritance, just the same as you have not paid the debt (see Rashi v. 14); render us therefore a little assistance by permitting us to pass through your land. (2) ולא נשתה מי באר NEITHER WILL WE DRINK OF THE WATER OF THE SPRINGS — He should have said “water of the cisterns (בורות)”; but this was what Moses meant to say: Although we have manna to eat, and a well of which to drink, (that which followed them through the wilderness), we will not drink of it, but we will buy food and water from you to your advantage. From here we may learn a rule for a guest (one lodging in an inn): although he has in his possession something to eat, he should yet purchase something from the local tradesman in order to benefit his host (Midrash Tanchuma, Chukat 12). (3) דרך המלך נלך וגו׳ WE WILL KEEP TO THE KING’S HIGHWAY etc. — we will muzzle our cattle, and so they will not turn aside into the fields on this side or that to eat (Midrash Tanchuma, Chukat 12).
(יז) אָ֚ז יָשִׁ֣יר יִשְׂרָאֵ֔ל אֶת־הַשִּׁירָ֖ה הַזֹּ֑את עֲלִ֥י בְאֵ֖ר עֱנוּ־לָֽהּ׃ (יח) בְּאֵ֞ר חֲפָר֣וּהָ שָׂרִ֗ים כָּר֙וּהָ֙ נְדִיבֵ֣י הָעָ֔ם בִּמְחֹקֵ֖ק בְּמִשְׁעֲנֹתָ֑ם וּמִמִּדְבָּ֖ר מַתָּנָֽה׃
(17) Then Israel sang this song: Spring up, O well—sing to it— (18) The well which the chieftains dug, Which the nobles of the people started With maces, with their own staffs. And from Midbar to Mattanah,
(יב) וַיֹּ֣אמֶר יְהֹוָה֮ אֶל־מֹשֶׁ֣ה וְאֶֽל־אַהֲרֹן֒ יַ֚עַן לֹא־הֶאֱמַנְתֶּ֣ם בִּ֔י לְהַ֨קְדִּישֵׁ֔נִי לְעֵינֵ֖י בְּנֵ֣י יִשְׂרָאֵ֑ל לָכֵ֗ן לֹ֤א תָבִ֙יאוּ֙ אֶת־הַקָּהָ֣ל הַזֶּ֔ה אֶל־הָאָ֖רֶץ אֲשֶׁר־נָתַ֥תִּי לָהֶֽם׃
(12) 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.”

(טו) רַבִּי טַרְפוֹן אוֹמֵר, הַיּוֹם קָצָר וְהַמְּלָאכָה מְרֻבָּה, וְהַפּוֹעֲלִים עֲצֵלִים, וְהַשָּׂכָר הַרְבֵּה, וּבַעַל הַבַּיִת דּוֹחֵק:

(15) Rabbi Tarfon said: the day is short, and the work is plentiful, and the laborers are indolent, and the reward is great, and the master of the house is insistent.
