Numbers 16:9-11

16:9 Does it seem too small a thing to you that the God of Israel has separated you from the community of Israel to bring you near to himself, to perform the service of the tabernacle of the Lord, and to stand before the community to minister to them? 16:10 He has brought you near and all your brothers, the sons of Levi, with you. Do you now seek ¹  the priesthood also? 16:11 Therefore you and all your company have assembled together against the Lord! And Aaron – what is he that you murmur against him?” ² 

[16:10]  ¹ tn The verb is the Piel perfect. There is no imperfect tense before this, which makes the construction a little difficult. If the vav (ו) is classified as a consecutive, then the form would stand alone as an equivalent to the imperfect, and rendered as a modal nuance such as “would you [now] seek,” or as a progressive imperfect, “are you seeking.” This latter nuance can be obtained by treating it as a regular perfect tense, with an instantaneous nuance: “do you [now] seek.”

[16:11]  ² 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.
