'Speech' in the Bible

And Moses said unto the LORD, O my Lord, I am not eloquent, neither heretofore, nor since thou hast spoken unto thy servant: but I am slow of speech, and of a slow tongue.

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.

But Moses spoke before the Lord, saying, “Behold, the sons of Israel have not listened to me; how then will Pharaoh listen to me, for I am unskilled in speech?”

But Moses said before the Lord, “Behold, I am unskilled in speech; how then will Pharaoh listen to me?”

Now concerning everything which I have said to you, be on your guard; do not mention the name of other gods [either in a blessing or in a curse]; do not let such speech be heard [coming] from your mouth.
