'Gain' in the Bible

Whoso is walking righteously, And is speaking uprightly, Kicking against gain of oppressions, Shaking his hands from taking hold on a bribe, Stopping his ear from hearing of blood, And shutting his eyes from looking on evil,

And the dogs are strong of desire, They have not known sufficiency, And they are shepherds! They have not known understanding, All of them to their own way they did turn, Each to his dishonest gain from his quarter:

For the iniquity of his dishonest gain, I have been wroth, and I smite him, Hiding -- and am wroth, And he goeth on turning back in the way of his heart.
