Luke 16:10

7 Then said he to another, And how much owest thou? And he said, A hundred measures of wheat. He saith unto him, Take thy bond, and write fourscore.

8 And his lord commended the unrighteous steward because he had done wisely: for the sons of this world are for their own generation wiser than the sons of the light.

9 And I say unto you, Make to yourselves friends by means of the mammon of unrighteousness; that, when it shall fail, they may receive you into the eternal tabernacles.

10 He that is faithful in a very little is faithful also in much: and he that is unrighteous in a very little is unrighteous also in much.

11 If therefore ye have not been faithful in the unrighteous mammon, who will commit to your trust the true [riches]?

12 And if ye have not been faithful in that which is another`s, who will give you that which is your own?

13 No servant can serve two masters: for either he will hate the one, and love the other; or else he will hold to one, and despise the other. Ye cannot serve God and mammon.
