'Revelation' in the Bible

so that you are not lacking in any gift, awaiting eagerly the revelation of our Lord Jesus Christ,

But now, brethren, if I come to you speaking in tongues, what will I profit you unless I speak to you either by way of revelation or of knowledge or of prophecy or of teaching?

What is the outcome then, brethren? When you assemble, each one has a psalm, has a teaching, has a revelation, has a tongue, has an interpretation. Let all things be done for edification.

But if a revelation is made to another who is seated, the first one must keep silent.
