'Flame' in the Bible

His head and hair were white like wool—white as snow—and His eyes like a fiery flame.

“Write to the angel of the church in Thyatira:“The Son of God, the One whose eyes are like a fiery flame and whose feet are like fine bronze, says:

His eyes were like a fiery flame, and many crowns were on His head. He had a name written that no one knows except Himself.
