Revelation 17:1-2, 5

Then one of the seven angels who had the seven bowls came and said to me, “Come, I will show you the judgment of the great prostitute who is seated on many waters, with whom the kings of the earth have committed sexual immorality, and with the wine of whose sexual immorality the dwellers on earth have become drunk.”

And on her forehead was written a name of mystery: “Babylon the great, mother of prostitutes and of earth’s abominations.”
