Jeremiah 3:3 (a) GOD is comparing the brazen effrontery of Israel to that type of a wicked woman. They sinned against GOD, and did not hide it. They rebelled against GOD's Word, and His law, with no regrets. (See also Ezekiel 16:28).

Revelation 17:1 (a) GOD spares no language in exposing the wickedness of the great false religions of the world, and particularly that cruel, voracious one that has its seat and headquarters in Rome. This religion has corrupted the nations of the world through the centuries. It offers its followers pleasure and protection from GOD's wrath while taking from them their money, their persons, their possessions, and their souls. (See also Revelation 19:2; Revelation 17:15).
