'Gain' in the Bible

“Behold, therefore, I strike My hands [together] at your dishonest gain which you have acquired and at the bloodshed which is among you.

Her princes within her are like wolves tearing and devouring the prey, shedding blood and destroying lives in order to get dishonest gain.

They come to you as people come, and they sit before you as My people, and they hear your words, but they do not practice them; for with their mouth they express loving devotion, but their heart goes after their (unlawful) gain.
