'Revelation' in the Bible

so that ye come short in no gift, awaiting the revelation of our Lord Jesus Christ;

And now, brethren, if I come to you speaking with tongues, what shall I profit you, unless I shall speak to you either in revelation, or in knowledge, or in prophecy, or in teaching?

What is it then, brethren? whenever ye come together, each of you has a psalm, has a teaching, has a tongue, has a revelation, has an interpretation. Let all things be done to edification.

But if there be a revelation to another sitting there, let the first be silent.
