Judges 13:2-6

And there was a man of Zorah, of the family of the Danites, whose name was Manoah; and his wife was infertile and had not given birth to any children.

Then the angel of the Lord appeared to the woman and said to her, “Behold now, you are infertile and have not given birth; but you will conceive and give birth to a son.

And now, be careful not to drink wine or strong drink, nor eat any unclean thing.

For behold, you will conceive and give birth to a son, and no razor shall come upon his head, for the boy shall be a Nazirite to God from the womb; and he will begin to save Israel from the hands of the Philistines.”

Then the woman came 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. So I did not ask him where he came from, nor did he tell me his name.
