I am working on properly translating the Norse phrase "Be Better", taken from the God of War phrase "We Must Be Better". I am not educated in the language, and my Google research says it is "verða betri" in Elder Futhark.

Could someone more skilled and aware than I confirm this?

I want to write "Never yield, never surrender" or "never yield, no surrender" to young futhark and i have been having a bit of trouble. I would prefer to have this written in the official language instead of just writing english with runes, but I can't find any reference to these words in ancient texts.
