'Unable' in the Bible

Then a demon-possessed man who was blind and unable to talk was brought to him. Jesus healed him so that the man could speak and see.

Large crowds came to him, bringing with them the lame, the blind, the crippled, those unable to talk, and many others. They placed them at his feet, and he healed them.

As a result, the crowd was amazed to see those who were unable to talk speaking, the crippled healed, the lame walking, and the blind seeing. So they praised the God of Israel.
