'Mute' in the Bible

Then the lame man will leap like a deer, and the tongue of the mute will sing; for waters will break out in the wilderness, and streams in the desert.

He was oppressed, yet when he was afflicted he didn't open his mouth. As a lamb that is led to the slaughter, and as a sheep that before its shearers is mute, so he didn't open his mouth.

His watchmen are blind, they are all without knowledge; they are all mute dogs, they can't bark; dreaming, lying down, loving to slumber.
