Luke 16:8-9; Luke 18:6

8 And the lord commended the unjust steward, because he had done wisely: for the children of this world are in their generation wiser than the children of light. 9 And I say unto you, Make to yourselves friends of the mammon of unrighteousness; that, when ye fail , they may receive you into everlasting habitations.
6 And the Lord said , Hear what the unjust judge saith .
