'Prophet' in the Bible

Every man who takes part in prayer, or gives teaching as a prophet, with his head covered, puts shame on his head.

But the word of the prophet gives men knowledge and comfort and strength.

But, now, my brothers, if I come to you using tongues, what profit will it be to you, if I do not give you a revelation, or knowledge, or the word of the prophet, or teaching?

If any man seems to himself to be a prophet or to have the Spirit, let him take note of the things which I am writing to you, as being the word of the Lord.
