Luke 1:18-20

18And Zacharias said to the angel, How shall I know this? for I am an old man, and my wife well advanced in years. 19And the angel answering said to him, I am Gabriel, who stand in the presence of God; and am sent to speak to thee, and to show thee these glad tidings. 20And, behold, thou shalt be dumb, and not able to speak, until the day that these things shall be performed, because thou believest not my words, which shall be fulfilled in their season.
