Mammon is the demon of greed. He is powerful and can corrupt even the purest souls. Mammon in Hebrew means money and in modern Hebrew wealth. Since Mammon is so powerful he is often referred to as one of the 7 princes of hell and Satan's son. Jesus mentioned him in a phrase: "You can not serve both God and Mammon." That means Jesus himself compared Mammon's influential power to God's.
Ave Satana, Heil Mammon, Heil Lilith.
