Judges 13:15-18

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. Manoah said to the Angel of the LORD, “What is your name, so that when your words come true, we may honor you?” But the Angel of the LORD said to him, “Why do you ask my name, seeing it is wonderful (miraculous)?” [Is 9:6]
