'Eloquent' 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."

Then the LORD was angry with Moses and said, "There's your brother Aaron, a descendant of Levi, isn't there? I know that he certainly is eloquent. Right now he's coming to meet you and he will be pleased to see you.
