Judges 13:2-5

And there was a certain man of Zorah, of the family of the Danites, whose name was Manoah; and his wife was infertile and had no children. And the Angel of the LORD appeared to the woman and said to her, “Behold, you are infertile and have no children, but you shall conceive and give birth to a son. Therefore, be careful not to drink wine or [any other] intoxicating drink, and do not eat anything [ceremonially] unclean. For behold, you shall conceive and give birth to a son. No razor shall come upon his head, for the boy shall be a Nazirite [dedicated] to God from birth; and he shall begin to rescue Israel from the hands of the Philistines.”
