'Edification' in the Bible

But one who prophesies speaks to men for edification and exhortation and consolation.

So also you, since you are zealous of spiritual gifts, seek to abound for the edification of the church.

What is the outcome then, brethren? When you assemble, each one has a psalm, has a teaching, has a revelation, has a tongue, has an interpretation. Let all things be done for edification.
