Mammon
Luke 16:9
Therefore, I tell you, make friends for yourselves by using worldly wealth, so that when it fails [i.e., when you run out of money] they [i.e., the friends you made with its wise and benevolent use] may welcome you into the eternal [i.e., heavenly] dwelling places. [Note: The idea here seems to be that by your shrewd use of material possessions for the benefit of others, you are actually storing up treasures for yourself in heaven].
1 Timothy 6:9
But those people who want to get rich fall into temptation and a trap and into many foolish and harmful desires, which plunge people into ruin and [spiritual] destruction.
