'Edification' in the Bible

Let each one of us please his neighbour with a view to what is good, to edification.

But he that prophesies speaks to men in edification, and encouragement, and consolation.

Now I desire that ye should all speak with tongues, but rather that ye should prophesy. But greater is he that prophesies than he that speaks with tongues, unless he interpret, that the assembly may receive edification.

Thus ye also, since ye are desirous of spirits, seek that ye may abound for the edification of the assembly.

What is it then, brethren? whenever ye come together, each of you has a psalm, has a teaching, has a tongue, has a revelation, has an interpretation. Let all things be done to edification.

Let no corrupt word go out of your mouth, but if there be any good one for needful edification, that it may give grace to those that hear it.
