'Gains' in the Bible

He who corrects a scoffer gains abuse for himself, and he who rebukes the wicked {gets hurt}.

He who ignores instruction despises himself, but he who hears admonition gains heart.

When prosperity increases, those who consume it increase. {So its owner gains nothing, except to see his wealth before it is spent}.

For what will a person be benefited if he gains the whole world but forfeits his life? Or what will a person give in exchange for his life?

For what is a person benefited [if he] gains the whole world but loses or forfeits himself?
