Revelation 2:9 – “I know your tribulation and your poverty (but you are rich), and the blasphemy by those who say they are Jews and are not, but are a synagogue of Satan.”
3:9 – “Behold, I will cause those of the synagogue of Satan, who say that they are Jews and are not, but lie – I will make them come and bow down at your feet, and make them know that I have loved you.”
