The Speaker: Who is this coming up from the desert like a column of smoke, like a fragrant billow of myrrh and frankincense, every kind of fragrant powder of the traveling merchants?

The speaker went on to say, "This is a curse traveling across the whole earth. For example, according to the curse whoever steals will be removed from the community; or on the other hand (according to the curse) whoever swears falsely will suffer the same fate."

They began to call Barnabas Zeus and Paul Hermes, because he was the chief speaker.

Now a Jew named Apollos, a native of Alexandria, arrived in Ephesus. He was an eloquent speaker, well-versed in the scriptures.
