Acts 19:34
But when they knew that he was a Jew, all with one voice about the space of two hours cried out, Great is Diana of the Ephesians.
But when they knew that he was a Jew,.... And so equally an enemy to their idolatry, as Paul and his companions were, whether he was a Christian or not.
all with one voice about the space of two hours cried out; all that were in the theatre lift up their voices at once to prevent Alexander's apology, or at least its being heard; and which they continued about two hours, which was a long time to keep hallooing out,
Great is Diana of the Ephesians; See Gill on "Acts 19:28".
