Judges 13:13-16

The Angel of the LORD said to Manoah, “The woman must pay attention to everything that I said to her. She may not eat anything that comes from the vine nor drink wine or [any other] intoxicating drink, nor eat anything [ceremonially] unclean. She shall observe everything that I commanded her.” Then Manoah said to the Angel of the LORD, “Please let us detain you and let us prepare a young goat for you [to eat].” The Angel of the LORD said to Manoah, “Though you detain me, I will not eat your food, but if you prepare a burnt offering, offer it to the LORD.” For Manoah did not know that he was the Angel of the LORD.
