Read Luke 1:22 Using Other Translations
And when he came out, he could not speak unto them: and they perceived that he had seen a vision in the temple: for he beckoned unto them, and remained speechless.
And when he came out, he was unable to speak to them, and they realized that he had seen a vision in the temple. And he kept making signs to them and remained mute.
When he finally did come out, he couldn’t speak to them. Then they realized from his gestures and his silence that he must have seen a vision in the sanctuary.
