Now the evening before the man arrived, the hand of the LORD was on me, and he opened my mouth before the man came to me in the morning. So my mouth was opened and I was no longer silent.

AMP
Now the hand of the LORD was upon me in the evening, afore he that was escaped came; and had opened my mouth, until he came to me in the morning; and my mouth was opened, and I was no more dumb.
