“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.”
And the people waited for Zacharias, and marveled that he lingered so long in the temple. But when he came out, he could not speak to them; and they perceived that he had seen a vision in the temple, for he beckoned to them and remained speechless.
So it was, as soon as the days of his service were completed, that he departed to his own house. Now after those days his wife Elizabeth conceived; and she hid herself five months, saying, “Thus the Lord has dealt with me, in the days when He looked on me, to take away my reproach among people.” Luke 1:18-25 NKJV
