Judges 13:6-7

6Then the woman came and told her husband, saying, A man of God came unto me, and his countenance was like the countenance of the angel of God, very terrible; and I asked him not whence he was, neither told he me his name:

7but he said unto me, Behold, thou shalt conceive, and bear a son; and now drink no wine nor strong drink, and eat not any unclean thing: for the child shall be a Nazirite unto God from the womb to the day of his death.
