'Edification' in the Bible

Let each one of us please his neighbor for his good, for the purpose of edification.

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.

Have you been thinking all this time that we are defending ourselves to you? We are speaking in Christ before God, and all [these things], dear friends, [are] for your edification.
