Stammering

“The mind of the rash will know and understand, and the stammering tongue will speak clearly and fluently.”

“You will no longer see the insolent, a people whose speech is unintelligible, who stammer in a language you cannot understand.”

““Please, Lord,” Moses replied, “I have never been eloquent, neither in the past nor since You have spoken to Your servant, for I am slow of speech and tongue.””
