I was reading Num 19:10 and it says that the law would be a permanent "statute" (KJV). 

> The man who gathers up the ashes of the heifer must also wash his
> clothes, and he too will be unclean till evening. This will be a
> lasting ordinance both for the Israelites and for the foreigners
> residing among them.

What exactly does this mean in light of the new covenant? Is it still permanent? Does it still apply? If it was permanent how does the new covenant make it not permanent?

There are many examples as well such as Lev 3:17, 6:22, Num 16:31, 34, 29, 17:7, 19:21, 10:8, 18:23, 23:31, 15:15, Ex 28:43, 29:9, etc.
