Luke 16:9-13

9And I say to you, Make to yourselves friends with the mammon of unrighteousness, that when it fails ye may be received into the eternal tabernacles.

10He that is faithful in the least is faithful also in much; and he that is unrighteous in the least is unrighteous also in much.

11If therefore ye have not been faithful in the unrighteous mammon, who shall entrust to you the true?

12and if ye have not been faithful in that which is another's, who shall give to you your own?

13No servant can serve two masters, for either he will hate the one and will love the other, or he will cleave to the one and despise the other. Ye cannot serve 1God and mammon.
