I know [about] your suffering and your poverty (but you are [really] rich), and the slander of those who say they are Jews, though they [really] are not, but are a synagogue of Satan [i.e., they claimed to be an assembly of God's people, but in reality were serving Satan].

Look at those who belong to the synagogue of Satan [See 2:9]; they claim to be Jews, yet they are not, but are lying. Watch, I will make them come and bow down at your feet [in respect] and [they will] know that I have loved you.
