Luke 1:18-20

18And Zacharias said to the angel, “How will I be certain of this? For I am an old man and my wife is advanced in age.”

19The angel replied and said to him, “I am Gabriel; I stand and minister in the [very] presence of God, and I have been sent [by Him] to speak to you and to bring you this good news.

20Listen carefully, you will be continually silent and unable to speak until the day when these things take place, because you did not believe what I told you; but my words will be fulfilled at their proper time.”
