'Unless' in the Bible

I wish all of you spoke in other languages, but even more that you prophesied. The person who prophesies is greater than the person who speaks in languages, unless he interprets so that the church may be built up.

But now, brothers, if I come to you speaking in other languages, how will I benefit you unless I speak to you with a revelation or knowledge or prophecy or teaching?

In the same way, unless you use your tongue for intelligible speech, how will what is spoken be known? For you will be speaking into the air.

You are also saved by it, if you hold to the message I proclaimed to you—unless you believed for no purpose.

Foolish one! What you sow does not come to life unless it dies.
