"Zacharias said to the angel, 'How will I know this for certain? For I am an old man and my
wife is advanced in years.' The angel answered and said to him, 'I am Gabriel, who stands in the presence of God,
and I have been sent to speak to you and to bring you this good news. And behold, you shall be silent and unable
to speak until the day when these things take place, because you did not believe my words, which will be fulfilled
in their proper time.'" (Luke 1:18-20)
