'Revelation' in the Bible

Indeed, brothers, if I come to you speaking in foreign languages, what good will I be to you unless I speak to you in some revelation, knowledge, prophecy, or teaching?

What, then, does this mean, brothers? When you gather, everyone has a psalm, teaching, revelation, foreign language, or interpretation. Everything must be done for upbuilding.

If a revelation is made to another person who is seated, the first person should be silent.
