'Flame' in the Bible

And his head and his hair were white like wool, as white as snow; and his eyes were as a flame of fire;

And to the angel of the church in Thyatira say: These things says the Son of God, whose eyes are like a flame of fire, and his feet like polished brass:

And at the sounding of the third angel, there went down from heaven a great star, burning like a flame, and it came on a third part of the rivers, and on the fountains of water.

And his eyes are a flame of fire, and crowns are on his head; and he has a name in writing, of which no man has knowledge but himself.
