'Gains' in the Bible

So are the ways of everyone who gains by violence;It takes away the life of its possessors.

How blessed is the man who finds wisdomAnd the man who gains understanding.

Ill-gotten gains do not profit,But righteousness delivers from death.

For what will it profit a man if he gains the whole world and forfeits his soul? Or what will a man give in exchange for his soul?

For what is a man profited if he gains the whole world, and loses or forfeits himself?
