ISB ~ Revelation 17 v4

scarlet … gold:Jeremiah once described Judah and Jerusalem as a harlot (Jer 2:20) dressed in scarlet and decked in gold finery (Jer 4:30). Ezekiel likewise pictured Jerusalem as a young woman arrayed in gold and fine linen (Ezek 16:13) who became a harlot (Ezek 16:2, 15).

golden cup:The image comes from Jer 51:7, which depicts Babylon as a golden cup filled with the wine of madness.
