'Gain' in the Bible

Behold, therefore, I have struck my hand at your dishonest gain which you have made, and at your blood which has been in the midst of you.

Her princes in its midst are like wolves ravening the prey, to shed blood, [and] to destroy souls, that they may get dishonest gain.

They come to you as the people come, and they sit before you as my people, and they hear your words, but don't do them; for with their mouth they show much love, but their heart goes after their gain.
