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.
for Manoah knew not that he was an angel of the Lord; he took him to be a man, a prophet sent of God, and not an angel; and much less the uncreated one, to whom as such only the sacrifice could be offered.
