'Speechless' in the Bible

So he said to him, ‘Friend, how did you get in here without wedding clothes?’ The man was speechless.

When he did come out, he could not speak to them. Then they realized that he had seen a vision in the sanctuary. He kept making signs to them and remained speechless.

The men who were traveling with him stood speechless, hearing the sound but seeing no one.

but received a rebuke for his transgression: A donkey that could not talk spoke with a human voice and restrained the prophet’s irrationality.
