Numbers 16:19

And Korah gathered all the congregation— The rebellious spirit of Korah and his company had infected the whole body of Israel, always prone to murmur, and inclined to throw off the authority of Moses and Aaron. The Lord threatens to destroy them all, Numbers 16:21 but Moses and Aaron intercede for them; Numbers 16:22 and not only so, but they exhort such as feared the Lord to separate themselves from these wicked men, Numbers 16:26 which accordingly they did, and so saved themselves from the destruction which overwhelmed Korah and the rest, Numbers 16:33.
