Fourth Babylon

The fourth Babylon is rising now—also called “the Kingdom of Tyre” in the ancient world, in the prophetic books. It is the End-Time worldwide economic system that will enslave the world through commerce, trade, and unjust usury (interest).
Money is the god that many have chosen instead of the Lord God. Mammon shall enslave all that will not bow their knee at the Cross and surrender all for the Lordship and Kingdom of our God and His Christ.
He also forced everyone, small and great, rich and poor, free and slave, to receive a mark on his right hand or on his forehead, so that no one could buy or sell unless he had the mark, which is the name of the beast or the number of his name.

Rev 13:16-17 NIV
