Bamidbar (Numbers) Chapter 17

9God spoke to Moses, saying:   טוַיְדַבֵּ֥ר יְהֹוָ֖ה אֶל־משֶׁ֥ה לֵּאמֹֽר:
10“Remove yourselves from this community, and I will consume them in an instant.” They fell on their faces.   יהֵרֹ֗מּוּ מִתּוֹךְ֙ הָֽעֵדָ֣ה הַזֹּ֔את וַֽאֲכַלֶּ֥ה אֹתָ֖ם כְּרָ֑גַע וַיִּפְּל֖וּ עַל־פְּנֵיהֶֽם:
11Moses said to Aaron, “Take the fire-pan, put fire from the top of the Altar in it, place incense in it, and take it quickly to the community and atone for them, for wrath has gone forth from God, and the plague has begun.”   יאוַיֹּ֨אמֶר משֶׁ֜ה אֶל־אַֽהֲרֹ֗ן קַ֣ח אֶת־הַ֠מַּחְתָּ֠ה וְתֶן־עָלֶ֨יהָ אֵ֜שׁ מֵעַ֤ל הַמִּזְבֵּ֨חַ֙ וְשִׂ֣ים קְטֹ֔רֶת וְהוֹלֵ֧ךְ מְהֵרָ֛ה אֶל־הָֽעֵדָ֖ה וְכַפֵּ֣ר עֲלֵיהֶ֑ם כִּֽי־יָצָ֥א הַקֶּ֛צֶף מִלִּפְנֵ֥י יְהֹוָ֖ה הֵחֵ֥ל הַנָּֽגֶף:
וְכַפֵּר עֲלֵיהֶם - And atone for them. This secret the Angel of Death had conveyed to Moses when he had ascended to heaven to receive the Torah, namely, that incense can halt a plague, as is stated in Tractate Shabbat. 1   וְכַפֵּר עֲלֵיהֶם.  רָז זֶה מָסַר לוֹ מַלְאַךְ הַמָּוֶת כְּשֶׁעָלָה לָרָקִיעַ, שֶׁהַקְּטֹרֶת עוֹצֵר הַמַּגֵּפָה, כִּדְאִיתָא בְמַסֶּכֶת שַׁבָּת (דף פ"ט):
12Aaron took it, just as Moses had said, and he ran into the midst of the community, and indeed, the plague had begun among the people. He placed the incense on it and atoned for the people.   יבוַיִּקַּ֨ח אַֽהֲרֹ֜ן כַּֽאֲשֶׁ֣ר | דִּבֶּ֣ר משֶׁ֗ה וַיָּ֨רָץ֙ אֶל־תּ֣וֹךְ הַקָּהָ֔ל וְהִנֵּ֛ה הֵחֵ֥ל הַנֶּ֖גֶף בָּעָ֑ם וַיִּתֵּן֙ אֶת־הַקְּטֹ֔רֶת וַיְכַפֵּ֖ר עַל־הָעָֽם:
13He stood between the dead and the living, and the plague ceased.   יגוַיַּֽעֲמֹ֥ד בֵּֽין־הַמֵּתִ֖ים וּבֵ֣ין הַֽחַיִּ֑ים וַתֵּֽעָצַ֖ר הַמַּגֵּפָֽה:
וַיַּֽעֲמֹד בֵּֽין־הַמֵּתִים וגו' - He stood between the dead…. 

i.e., He took hold of the Angel of Death and detained him against his will. The Angel said to him: “Allow me to carry out my mission!” Aaron replied: “Moses commanded me to restrain you!” The Angel said: “I am the messenger of the Omnipresent, and you are only the messenger of Moses!” Aaron replied: “Moses says nothing of his own accord, only what he has heard from the Almighty. If you do not believe this, the Holy One, blessed be He, and Moses are at the entrance of the Tent of Meeting. Come with me and ask them!” And this is what it says: “Aaron returned to Moses.” 2

Another explanation: Why was the plague halted through the incense? Because the Israelites were slandering and maligning the incense, saying that it is a lethal potion, for through it Nadav and Avihu died, and through it 250 men were burned. The Holy One, blessed be He, therefore said: “See that it can halt a plague, and it is only sin that brings death.”

  וַיַּֽעֲמֹד בֵּֽין־הַמֵּתִים וגו'.  אָחַז אֶת הַמַּלְאָךְ וְהֶעֱמִידוֹ עַל כָּרְחוֹ, אָמַר לוֹ הַמַּלְאָךְ, הַנַּח לִי לַעֲשׂוֹת שְׁלִיחוּתִי, אָמַר לוֹ מֹשֶׁה צִוַּנִי לְעַכֵּב עַל יָדְךָ, אָמַר לוֹ אֲנִי שְׁלוּחוֹ שֶׁל מָקוֹם וְאַתָּה שְׁלוּחוֹ שֶׁל מֹשֶׁה, אָמַר לוֹ אֵין מֹשֶׁה אוֹמֵר כְּלוּם מִלִּבּוֹ אֶלָּא מִפִּי הַגְּבוּרָה, אִם אֵין אַתָּה מַאֲמִין, הֲרֵי הַקָּדוֹשׁ בָּרוּךְ הוּא וּמֹשֶׁה אֶל פֶּתַח אֹהֶל מוֹעֵד, בֹּא עִמִּי וּשְׁאַל, וְזֶהוּ שֶׁנֶּאֱמַר וישב אהרן אל משה; דָּבָר אַחֵר, לָמָּה בַקְּטֹרֶת? לְפִי שֶׁהָיוּ יִשְׂרָאֵל מְלִיזִים וּמְרַנְּנִים אַחַר הַקְּטֹרֶת לוֹמַר סַם הַמָּוֶת הוּא — עַל יָדוֹ מֵתוּ נָדָב וַאֲבִיהוּא, עַל יָדוֹ נִשְׂרְפוּ חֲמִשִּׁים וּמָאתַיִם אִישׁ — אָמַר הַקָּדוֹשׁ בָּרוּךְ הוּא, תִּרְאוּ שֶׁעוֹצֵר מַגֵּפָה הוּא וְהַחֵטְא הוּא הַמֵּמִית (מכילתא שמות י"ז):
14The number of people who died in the plague was 14,700, besides those who died because of the matter of Korach.   ידוַיִּֽהְי֗וּ הַמֵּתִים֙ בַּמַּגֵּפָ֔ה אַרְבָּעָ֥ה עָשָׂ֛ר אֶ֖לֶף וּשְׁבַ֣ע מֵא֑וֹת מִלְּבַ֥ד הַמֵּתִ֖ים עַל־דְּבַר־קֹֽרַח:
15Aaron returned to Moses, to the entrance to the Tent of Meeting, and the plague was stopped.   טווַיָּ֤שָׁב אַֽהֲרֹן֙ אֶל־משֶׁ֔ה אֶל־פֶּ֖תַח אֹ֣הֶל מוֹעֵ֑ד וְהַמַּגֵּפָ֖ה נֶֽעֱצָֽרָה:
