(1) Now Korah, son of Izhar son of Kohath son of Levi, betook himself, along with Dathan and Abiram sons of Eliab, and On son of Peleth—descendants of Reuben — (2) to rise up against Moses, together with two hundred and fifty Israelites, chieftains of the community, chosen in the assembly, men of repute. (3) They combined against Moses and Aaron and said to them, “You have gone too far! For all the community are holy, all of them, and ה' is in their midst. Why then do you raise yourselves above The Lord's congregation?” (4) When Moses heard this, he fell on his face. (5) Then he spoke to Korah and all his company, saying, “Come morning, The Lord will make known who is [God’s] and who is holy by granting direct access; the one whom [God] has chosen will be granted access. (6) Do this: You, Korah and all your band, take fire pans, (7) and tomorrow put fire in them and lay incense on them before ה'. Then the candidate whom ה' chooses, he shall be the holy one. You have gone too far, sons of Levi!” (8) Moses said further to Korah, “Hear me, sons of Levi. (9) Is it not enough for you that the God of Israel has set you apart from the community of Israel and given you direct access, to perform the duties of יהוה’s Tabernacle and to minister to the community and serve them? (10) Now that [God] has advanced you and all your fellow Levites with you, do you seek the priesthood too? (11) Truly, it is against ה' that you and all your company have banded together. For who is Aaron that you should rail against him?” (12) Moses sent for Dathan and Abiram, sons of Eliab; but they said, “We will not come!
כָּל הַדְּבָרִים הָאֵלּוּ פִּיֵּס משֶׁה לְקֹרַח, וְאֵין אַתְּ מוֹצֵא שֶׁהֱשִׁיבוֹ דָּבָר, לְפִי שֶׁהָיָה פִּקֵּחַ בְּרִשְׁעוֹ, אָמַר אִם אֲנִי מְשִׁיבוֹ יוֹדֵעַ אֲנִי בּוֹ שֶׁהוּא חָכָם גָּדוֹל וְעַכְשָׁו יְקַפְּחֵנִי בִּדְבָרָיו וַאֲנִי מִתְרַצֶּה לוֹ בְּעַל כָּרְחִי, מוּטָב שֶׁלֹא אֶזָקֵק לוֹ. כְּשֶׁרָאָה משֶׁה שֶׁאֵין בּוֹ תּוֹעֶלֶת פֵּרַשׁ הֵימֶנּוּ.
With all these words Moses [tried to] appease Korah, but you do not find that he gave him any answer. Because he was clever in his wickedness, he said [to himself], “If I answer him, I know that, since he has great wisdom, he will now overwhelm me with his words and seduce me into being reconciled with him against my will. It is [hence] better that I not respond to him.” When Moses saw that there was nothing to be gained with him, he withdrew from him.
