The beginning of the story of Samson:
So the woman came and told her husband, saying, “A Man of God came to me, and His countenance was like the countenance of the Angel of God, very awesome; but I did not ask Him where He was from, and He did not tell me His name. 7 And He said to me, ‘Behold, you shall conceive and bear a son. Now drink no wine or similar drink, nor eat anything unclean, for the child shall be a Nazirite to God from the womb to the day of his death.’
