“And the woman was arrayed in purple and scarlet colour, and decked with gold and precious stones and pearls, having a golden cup in her hand full of abominations and filthiness of her fornication:”
King James Version (KJV)
17:4 And the woman was arrayed - With the utmost pomp and magnificence. In purple and scarlet - These were the colours of the imperial habit: the purple, in times of peace; and the scarlet, in times of war. Having in her hand a golden cup - Like the ancient Babylon, #Jer 51:7|. Full of abominations - The most abominable doctrines as well as practices.
Re 17:4 And the woman was arrayed in purple and scarlet colour. The color of royalty. And decked with gold and precious stones and pearls. Her jewels and gold indicate enormous wealth. Having a golden cup in her hand. A golden censer in the hands of an angel represents by its incense the prayers of those who belong to the true church (Re 8:4). This symbol of the false church has a cup full of abominations instead. See Jer 51:7.
