Luke 1:7, 18, 36

They had no children because Elizabeth was unable to conceive, and they were both very old.

Zechariah said to the angel, “How can I be sure this will happen? I’m an old man now, and my wife is also well along in years.”

What’s more, your relative Elizabeth has become pregnant in her old age! People used to say she was barren, but she has conceived a son and is now in her sixth month.
