Judges 13:2-3,24:

And there was a certain man of Zorah, of the family of the Danites, whose name was Manoah; and his wife was barren, and bare not.
And the angel of the LORD appeared unto the woman, and said unto her, Behold now, thou art barren, and bearest not: but thou shalt conceive, and bear a son.
...
And the woman bare a son, and called his name Samson: and the child grew, and the LORD blessed him.
