Judges 13:17-20

And Manoah said unto the angel of the LORD, What is thy name, that when thy sayings come to pass we may do thee honour? And the angel of the LORD said unto him, Why askest thou thus after my name, seeing it is secret? So Manoah took a kid with a meat offering, and offered it upon a rock unto the LORD: and the angel did wondrously; and Manoah and his wife looked on. For it came to pass, when the flame went up toward heaven from off the altar, that the angel of the LORD ascended in the flame of the altar. And Manoah and his wife looked on it, and fell on their faces to the ground.
