Judges 13:2-7

2And 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.

3And 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.

4Therefore, be careful not to drink wine or [any other] intoxicating drink, and do not eat anything [ceremonially] unclean.

5For 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.”

6Then the woman went and told her husband, saying, “A Man of God came to me and his appearance was like the appearance of the Angel of God, very awesome. I did not ask Him where he came from, and he did not tell me his name.

7But He said to me, ‘Behold, you shall conceive and give birth to a son, and now you shall not drink wine or [any other] intoxicating drink, nor eat anything [ceremonially] unclean, for the boy shall be a Nazirite to God from birth to the day of his death.’ ”
