'Flame' in the Bible

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

And to the angel of the church in Thyatira write: These things saith the Son of God, who hath his eyes like a flame of fire, and his feet are like unto burnished brass:

And his eyes are a flame of fire, and upon his head are many diadems; and he hath a name written which no one knoweth but he himself.
