Luke 1:18-20

And Zacharias said to the angel, “How shall I know this? For I am an old man, and my wife is well advanced in years.” And the angel answered and said to him, “I am Gabriel, who stands in the presence of God, and was sent to speak to you and bring you these glad tidings. But behold, you will be mute and not able to speak until the day these things take place, because you did not believe my words which will be fulfilled in their own time.”
