Mammon 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."
