'Edification' in the Bible

But the one who prophesies speaks to people edification and encouragement and consolation.

Now I want you all to speak with tongues, but even more that you may prophesy. The one who prophesies [is] greater than the one who speaks with tongues, unless he interprets, in order that the church may receive edification.

In this way also you, since you are zealous of spiritual [gifts], seek for the edification of the church, in order that you may abound.

{Therefore what should you do}, brothers? Whenever you come together, each one of you has a psalm, has a teaching, has a revelation, has a tongue, has an interpretation. All [things] must be [done] for edification.
