'Teaching' in the Bible

But now, brethren, if I come unto you speaking with tongues, what shall I profit you, unless I speak to you either by way of revelation, or of knowledge, or of prophesying, or of teaching?

What is it then, brethren? When ye come together, each one hath a psalm, hath a teaching, hath a revelation, hath a tongue, hath an interpretation. Let all things be done unto edifying.
