'Synagogue of Satan' in the Bible

I know thy tribulation, and destitution, nevertheless, thou art, rich, and the profane speech from among them who affirm that they themselves are, Jews, and they are not, but a synagogue of Satan.

Lo! I give them of the synagogue of Satan, who are affirming themselves to be, Jews, and are not, - but say what is false, - lo! I will cause them, that they shall have come, and shall bow down before thy feet, and shall get to know that, I, loved thee.
