'Speaker' in the Bible

And they called Barnabas, Jupiter; and Paul, Mercurius, 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.

Therefore, if I do not know the meaning of the language, I will be a foreigner to the speaker, and the speaker will be a foreigner to me.

If an interpreter is not present, the speaker should remain silent in the church and speak to himself and God.
