'Speech' in the Bible

Then Moses told the LORD, "Please, LORD, I'm not eloquent. I never was in the past nor am I now since you spoke to your servant. In fact, I talk too slowly and I have a speech impediment."

Now, go! I myself will help you with your speech, and I'll teach you what you are to say."

You're to speak to him and tell him what to say. I'll help both you and him with your speech, and I'll teach both of you what you are to do.
