'Up building' in the Bible

So then let is eagerly pursue the things that make for peace and the upbuilding of each other.

Let each one of us try to make his neighbor happy for his good, unto his upbuilding.

So also in your case, since you are ambitious for spiritual gifts, seek to excel in them for the upbuilding of the church.

Do you think that all this time I am defending myself to you? It is before the presence of God that I am speaking in Christ; and all, beloved, for your upbuilding.

From your lips let no evil words come forth, but such as occasion warrants, such as are good for upbuilding and give a blessing to the hearers.
