Luke 1:13, 20, 36

But the angel said to him, “Zechariah, don’t be afraid. God has heard your prayer. Your wife, Elizabeth, will give birth to a son, and you will name him John.

Now, listen! You will not be able to speak until the day these things happen, because you did not believe what I told you. But they will really happen.”

Now Elizabeth, your relative, is also pregnant with a son though she is very old. Everyone thought she could not have a baby, but she has been pregnant for six months.
