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.
So Manoah took the kid with a meal offering, and he offered it on a rock unto the LORD: and the angel of the LORD did wondrously; while Manoah and his wife looked on ( Judges 13:19 ).
