'Gain' in the Bible

If a man denounces his friends for personal gain, the eyes of his children will fail.

He gives back the ill-gotten gain without assimilating it; he will not enjoy the wealth from his commerce.

Who is the Almighty, that we should serve him? What would we gain if we were to pray to him?'

Is it of any special benefit to the Almighty that you should be righteous, or is it any gain to him that you make your ways blameless?

But you say, 'What will it profit you,' and, 'What do I gain by not sinning?'
