Judges 13:19-21

American Standard Version

¹⁹ So Manoah took the kid with the meal-offering, and offered it upon the rock unto Jehovah: and the angel did wondrously, and Manoah and his wife looked on. ²⁰ For it came to pass, when the flame went up toward heaven from off the altar, that the angel of Jehovah ascended in the flame of the altar: and Manoah and his wife looked on; and they fell on their faces to the ground.

²¹ But the angel of Jehovah did no more appear to Manoah or to his wife. Then Manoah knew that he was the angel of Jehovah.
