'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?”
