Judges 13:3-5

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.”
