The angel of Yahweh said to Manoah, Though you detain me, I won't eat of your bread; and if you will make ready a burnt offering, you must offer it to Yahweh. For Manoah didn't know that he was the angel of Yahweh.
Evidently Manoah also assumed that the Angel of the Lord was a prophet (Judges 13:17). The Angel told Manoah that His name was "wonderful" (Heb. pil’i, Judges 13:18, "beyond understanding," NIV).
