How did zechariah react to his barren wife becoming pregnant?

Zechariah acted in disbelief.

Angel Gabriel appeared to Zechariah in theTemple and he told Zechariah that his wife Elizabeth (who had been barren) were going to have a son named John. Zechariah doubted about that because they bith were old to conceived a son. Zechariah was punished for his disbelief and he remained silent until the child's birth.
