'Unless' in the Bible

Don't deprive one another, unless it is by consent for a season, that you may give yourselves to fasting and prayer, and may be together again, that Satan doesn't tempt you because of your lack of self-control.

Now I desire to have you all speak with other languages, but rather that you would prophesy. For he is greater who prophesies than he who speaks with other languages, unless he interprets, that the assembly may be built up.

But now, brothers, if I come to you speaking with other languages, what would I profit you, unless I speak to you either by way of revelation, or of knowledge, or of prophesying, or of teaching?

So also you, unless you uttered by the tongue words easy to understand, how would it be known what is spoken? For you would be speaking into the air.

by which also you are saved, if you hold firmly the word which I preached to you -- unless you believed in vain.

You foolish one, that which you yourself sow is not made alive unless it dies.
