Mammon (Aramaic: מָמוֹנָא, māmōnā) in the New Testament is commonly thought to mean money, material wealth, or any entity that promises wealth, and is associated with the greedy pursuit of gain. The Gospel of Matthew and the Gospel of Luke both quote Jesus using the word in a phrase often rendered in English as "You cannot serve both God and mammon."
In the Middle Ages, it was often personified and sometimes included in the seven princes of Hell, depicting greed.Mammon in Hebrew (ממון) means 'money'. The word was adopted to modern Hebrew to mean wealth.
