Mammon (măm'mon), wealth. A Chaldee or Syriac word used by our Lord in uttering two severe admonitions. In the one. Matthew 6:24, he would intend a carnal worldly possession-loving spirit, which unfits a man for the high service of God. In the second place, Luke 16:9, Luke 16:11, mammon is more explicitly wealth, called "mammon of unrighteousness" because it is the substance of a system, an avaricious system, which never could have existed had original righteousness not been lost.
