Cover art for The Longest Road lyrics by Morgan Page

Sorry to bother you, but English is not my native language and I can't understand the last verse.

"If you fill my cup with all you must To speak from something"

Could someone rephrase that or explain what it means?

Thanks

Translation

@kuroineko You're OK. I don't speak any other language but English and those lines make basically no sense to me either.
