Luke 1:18-20

And 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.” The 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. [Dan 8:16; 9:21] Listen 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.”
