'Edification' in the Bible

Each of us is to please his neighbor for his good, to his edification.

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.

Let no unwholesome word proceed from your mouth, but only such a word as is good for edification according to the need of the moment, so that it will give grace to those who hear.
