Aramaic mamona, 'wealth, property' — from the same root as amen: that in which one trusts. Left untranslated by Matthew ('You cannot be slaves to God and to Mammon,' 6:24) and by nearly every version since (NIV breaks ranks: 'money'). Not a Canaanite deity — capital personified by the sentence's own grammar: only masters have slaves. → first discussed at Matt 6:24
