For it happened, when the flame went up toward the sky from off the altar, that the angel of Yahweh ascended in the flame of the altar: and Manoah and his wife looked on; and they fell on their faces to the ground.
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 ).
