Korach had "250" on his side. How many did Moshe/Aharon have on their side?
What do the rabbis say?
The other side of the coin: How many "Elders of Israel" (Bamidbar 16:25) were among the "250" men that sided with Korach?
I am assuming that perhaps at least one person who sided with Korach was an Elder of Israel. In my mind, the Elders of Israel are at least נְשִׂיאֵי עֵדָה קְרִאֵי מוֹעֵד, אַנְשֵׁי-שֵׁם ( Numbers 16:2 ), unless of course, one corrects me and says that Elders of Israel need not be נְשִׂיאֵי עֵדָה קְרִאֵי מוֹעֵד, אַנְשֵׁי-שֵׁם.
