Luke 1:20-22

New Catholic Bible

²⁰ But now, because you did not believe my words, which will be fulfilled at their appointed time, you will lose your power of speech and will become mute until the day that these things take place.”

²¹ Meanwhile, the people were waiting for Zechariah and were surprised that he was delaying so long in the sanctuary. ²² When he did emerge, he could not speak to them, and they realized that he had seen a vision while he was in the sanctuary. He was only able to make signs to them, but he remained unable to speak.
