Judges 13:19-21

¹⁹So Manoah took the young goat with the grain offering and offered it on the rock to the Lord, and He performed wonders while Manoah and his wife looked on. ²⁰For it came about when the flame went up from the altar toward heaven, that the angel of the Lord ascended in the flame of the altar. When Manoah and his wife saw this, they fell on their faces to the ground. ²¹Now the angel of the Lord did not appear to Manoah or his wife again. Then Manoah knew that he was the angel of the Lord.
