Judges 13:2-7

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 Jehovah appeared unto the woman, and said unto her, Behold now, thou art barren, and bearest not; but thou shalt conceive, and bear a son. Now therefore beware, I pray thee, and drink no wine nor strong drink, and eat not any unclean thing: for, 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. Then 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: but 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.
