Apparently Korah didn’t understand the “burning bush incident”! Moses and Aaron were God’s anointed. They didn't need to be replaced. And did they not remember what happened to Miriam when she and Aaron challenged Moses' leadership?

Jude 1:10-11
Yet these men speak abusively against whatever they do not understand; and what things they do understand by instinct, like unreasoning animals-- these are the very things that destroy them. Woe to them! They have taken the way of Cain; they have rushed for profit into Balaam's error; they have been destroyed in Korah's rebellion.

God institutes the command to redeem the firstborn. The people are redeemed by paying a temple price. The holy animals are sacrificed. See any connections with Jesus here???

Notice that the Levites receive a tithe, a tenth from all the other tribes. This is a commanded tax. The Levites are then to give a tenth to Aaron. Part of the tithe that Aaron and his descendants are to receive is juice from a winepress, not wine itself. Remember, Aaron and his sons were not to consume fermented drink while serving at the tabernacle. Wow, God takes care of even the minute details!

When God does things, He certainly does it up right. There's that staff again! Are you paying attention to all these references to the all-important staff. Wouldn’t it have been enough to just have Aaron’s staff sprout? That was all He promised them to prove Aaron was His chosen one. And yet, He caused the staff to bud, to blossom, and to produce almonds! And overnight even!
Now, let’s see…what was that Scripture about God being able to do more than we ask for…oh yes, here it is.

Eph 3:20
Now to him who is able to do immeasurably more than all we ask or imagine, according to his power that is at work within us,

Tapped into His power lately???
