chabwIj nIHpu' Mike 'e' vISovbe'
I don't know whether Mike stole my pie.

I don't accept this translation.

That sentence can only mean:

"I don't know that Mike stole my pie."

I fail to see the difference in meaning. Both sentences take the proposition that Mike stole my pie and declare my lack of knowledge that it's true.
