'Gain' in the Bible

But her commercial gain and her prostitute’s wages will be dedicated to the Lord; it will not be treasured or stored up, but her commercial gain will become sufficient food and stately clothing for those who dwell (minister) in the presence of the Lord.

The fool (the good-for-nothing) will no longer be called noble,Nor the rogue said to be generous.

As for the rogue, his weapons are evil;He conceives wicked plansTo ruin the poor with lies,Even when the plea of the needy one is just and right.

He who walks righteously and speaks with integrity,Who rejects gain from fraud and from oppression,Who shakes his hand free from the taking of bribes,Who stops his ears from hearing about bloodshedAnd shuts his eyes to avoid looking upon evil;

And the dogs are greedy; they never have enough.They are shepherds who have no understanding;They have all turned to their own way,Each one to his unlawful gain, without exception.

“Because of the wickedness of his unjust gain I was angry and struck him;I hid My face and was angry,And he went on turning away and backsliding, in the way of his [own willful] heart.
