A certain man of Zorah, named Manoah, from the clan of the Danites, had a wife who was sterile and remained childless.  The angel of the LORD appeared to her and said, "You are sterile and childless, but you are going to conceive and have a son [Samson].
Judges 13:2-3

But they had no child, because Elizabeth was barren; and they were both well along in years...  When it was time for Elizabeth to have her baby, she gave birth to a son.  Her neighbors and relatives heard that the Lord had shown her great mercy, and they shared her joy.  On the eighth day they came to circumcise the child, and they were going to name him after his father Zechariah, but his mother spoke up and said, "No!  He is to be called John."
Luke 1:7, 57-60
