'Speechless' in the Bible

Moreover, He said to me, “Son of man, behold (listen carefully), I am going to break the staff of bread [that supports life] in Jerusalem; and they shall eat bread [rationed] by weight and [eat it] with anxiety and fear, and drink water by measure and [drink it] in horror [of the impending starvation],

On that day your mouth will be opened to him who escaped, and you will speak and no longer be mute. In this way you shall be a sign to them, and they will know [without any doubt] that I am the Lord.’”

Now the hand of the Lord had been upon me in the evening, before the refugees came. And He opened my mouth at the time they came to me in the morning; so my mouth was opened and I was no longer speechless.
