Berean Study Bible (BSB) - Revelation 2:9 >

I know your affliction and your poverty—though you are rich! And I am aware of the slander of those who falsely claim to be Jews, but are in fact a synagogue of Satan.

Textus Receptus (TR) - Revelation 2:9 >

Οἶδά σου τὰ ἔργα καὶ τὴν θλίψιν καὶ τὴν πτωχείαν, πλούσιος δὲ εἶ· καὶ τὴν βλασφημίαν τῶν λεγόντων Ἰουδαίους εἶναι ἑαυτούς, καὶ οὐκ εἰσίν, ἀλλὰ συναγωγὴ τοῦ Σατανᾶ.
