'Unless' in the Bible

I thank God that I have baptised none of you, unless Crispus and Gaius,

Do not withhold yourselves from each other unless you agree to do so just for a set time, in order to devote yourselves to prayer. Then you should come together again so that Satan does not tempt you through your lack of self-control.

I give you therefore to know, that no one, speaking in the power of the Spirit of God, says, Curse on Jesus; and no one can say, Lord Jesus, unless in the power of the Holy Spirit.

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?

It is similar for lifeless things that make a sound, like a flute or harp. Unless they make a distinction in the notes, how can what is played on the flute or harp be understood?

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.

By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.

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