'Flame' in the Bible

Then the angel of the Lord put out the stick which was in his hand, touching the meat and the cakes with the end of it; and a flame came up out of the rock, burning up the meat and the cakes: and the angel of the Lord was seen no longer.

And when the flame went up to heaven from the altar, the angel of the Lord went up in the flame of the altar, while Manoah and his wife were looking on; and they went down on their faces to the earth.

Now she had men waiting secretly in the inner room; and she said to him, The Philistines are on you, Samson. And the cords were broken by him as a twist of thread is broken when touched by a flame. So the secret of his strength did not come to light.
