Numbers 16:11

16:11 Therefore you and all your company have assembled together against the Lord! And Aaron – what is he that you murmur against him?” ¹ 

Numbers 16:32

16:32 and the earth opened its mouth and swallowed them, along with their households, and all Korah’s men, and all their goods.

[16:11]  ¹ sn The question indicates that they had been murmuring against Aaron, that is, expressing disloyalty and challenging his leadership. But it is actually against the Lord that they had been murmuring because the Lord had put Aaron in that position.
