'Speaker' in the Bible

But Moses said in the Lord’s presence: “If the Israelites will not listen to me, then how will Pharaoh listen to me, since I am such a poor speaker?”

But Moses replied in the Lord’s presence, “Since I am such a poor speaker, how will Pharaoh listen to me?”

Then I heard a holy one speaking, and another holy one said to the speaker, “How long will the events of this vision last—the daily sacrifice, the rebellion that makes desolate, and the giving over of the sanctuary and of the host to be trampled?”

And they started to call Barnabas, Zeus, and Paul, Hermes, because he was the main speaker.

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.
