Judges 13:16-18
13:16 The Lord’s messenger said to Manoah, “If I stay, I will not eat your food. But if you want to make a burnt sacrifice to the Lord, you should offer it.” (He said this because Manoah did not know that he was the Lord’s messenger.)
13:17 Manoah said to the Lord’s messenger, “Tell us your name, so we can honor you when your announcement comes true.”
13:18 The Lord’s messenger said to him, “You should not ask me my name, because you cannot comprehend it.”
