Manoah said to the angel of Yahweh, I pray you, let us detain you, that we may make ready a kid for you.
"The Angel of Jehovah did wondrously"  (Judges 13:19).  It is not so stated here, but the consumption of Manoah's offering by fire probably came about as it did when this same Angel of Jehovah touched Gideon's offering with the end of his staff, causing fire to come up out of the altar and devour the burnt-offering (Judges 6:21).  "The angel did wondrously" is probably a reference to the same kind of phenomenon that occurred here.
