the mammon of unrighteousness

the mammon of unrighteousness

wealth ill-used or ill-gained.
This biblical expression comes from Luke 16:9: ‘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’. Mammon ultimately comes from Hebrew mamon meaning ‘money or wealth’. In early use, it was used to refer to the devil of covetousness; it later was used as the personification of wealth regarded as an idol or an evil influence.
