'Dumb' in the Bible

As they were going out, a mute, demon-possessed man was brought to Him.

After the demon was cast out, the mute man spoke; and the crowds were amazed, and were saying, “Nothing like this has ever been seen in Israel.”

Then a demon-possessed man who was blind and mute was brought to Jesus, and He healed him, so that the mute man spoke and saw.

And large crowds came to Him, bringing with them those who were lame, crippled, blind, mute, and many others, and they laid them down at His feet; and He healed them.

So the crowd marveled as they saw the mute speaking, the crippled restored, and the lame walking, and the blind seeing; and they glorified the God of Israel.
