Revelation 2:9 (see description)

Study Revelation 3:9
It's an ancient trick, but not from the Jews;
(say they are Jews and are not) it is from Team Goat.

Revelation 2:9 “I know your works, tribulation, and poverty (but you are rich); and I know the blasphemy of those who say they are Jews and are not, but are a synagogue of Satan.

Revelation 3:9 Indeed I will make those of the synagogue of Satan, who say they are Jews and are not, but lie—indeed I will make them come and worship before your feet, and to know that I have loved you.
