'Prophecy' in the Bible

To another the working of miracles; to another prophecy; to another discerning of spirits; to another divers kinds of tongues; to another the interpretation of tongues:

And though I have the gift of prophecy, and understand all mysteries, and all knowledge; and though I have all faith, so that I could remove mountains, and have not charity, I am nothing.

Love never fails; but if there are gifts of prophecy, they will be done away; if there are tongues, they will cease; if there is knowledge, it will be done away.

for in part we know, and in part we prophecy;

Pursue the love, and seek earnestly the spiritual things, and rather that ye may prophecy,

and I wish you all to speak with tongues, and more that ye may prophecy, for greater is he who is prophesying than he who is speaking with tongues, except one may interpret, that the assembly may receive edification.

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 follows that speaking in other languages is intended as a sign, not for believers but for unbelievers. But prophecy is not for unbelievers but for believers.

and if all may prophecy, and any one may come in, an unbeliever or unlearned, he is convicted by all, he is discerned by all,
