'Dumb' in the Bible
But as these were going out, behold, they brought to him a dumb man possessed by a demon.
And the demon having been cast out, the dumb spake. And the crowds were astonished, saying, It has never been seen thus in Israel.
Then was brought to him one possessed by a demon, blind and dumb, and he healed him, so that the dumb man spake and saw.
and great crowds came to him, having with them lame, blind, dumb, crippled, and many others, and they cast them at his feet, and he healed them:
so that the crowds wondered, seeing dumb speaking, crippled sound, lame walking, and blind seeing; and they glorified the God of Israel.
And one out of the crowd answered him, Teacher, I brought to thee my son, who has a dumb spirit;
But Jesus, seeing that the crowd was running up together, rebuked the unclean spirit, saying to him, Thou dumb and deaf spirit, I command thee, come out of him, and enter no more into him.
But when he came out he could not speak to them, and they recognised that he had seen a vision in the temple. And he was making signs to them, and continued dumb.
And he was casting out a demon, and it was dumb; and it came to pass, the demon being gone out, the dumb man spoke. And the crowds wondered.
And the passage of the scripture which he read was this: He was led as a sheep to slaughter, and as a lamb is dumb in presence of him that shears him, thus he opens not his mouth.
Ye know that when ye were of the nations ye were led away to dumb idols, in whatever way ye might be led.
but had reproof of his own wickedness the dumb ass speaking with man's voice forbad the folly of the prophet.
