'Gain' in the Bible

Behold, therefore, I have smitten my hand at thy dishonest gain which thou hast made, and at thy blood which hath been in the midst of thee.

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

And they come unto thee as the people cometh, and they sit before thee as my people, and they hear thy words, but do them not; for with their mouth they show much love, but their heart goeth after their gain.
