'Edification' in the Bible

Let every one of us please his neighbour for his good to edification.

But he that prophesieth speaketh unto men to edification, and exhortation, and comfort.

For though I should boast somewhat more of our authority, which the Lord hath given us for edification, and not for your destruction, I should not be ashamed:

Therefore I write these things being absent, lest being present I should use sharpness, according to the power which the Lord hath given me to edification, and not to destruction.
