Judges 13:4-7

4Now therefore beware, I pray thee, and drink no wine nor strong drink, and eat not any unclean thing: 5for, lo, thou shalt conceive, and bear a son; and no razor shall come upon his head; for the child shall be a Nazirite unto God from the womb: and he shall begin to save Israel out of the hand of the Philistines. 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.
