'Gain' in the Bible

So are the ways of every one that is greedy of gain; It taketh away the life of the owners thereof.

He that is greedy of gain troubleth his own house; But he that hateth bribes shall live.

He that oppresseth the poor to increase his gain , And he that giveth to the rich,'shall come only to want.

The heart of her husband trusteth in her, And he shall have no lack of gain.
