'Flames' in the Bible

He makes his messengers winds; his servants flames of fire.

For, behold, Yahweh will come with fire, and his chariots shall be like the whirlwind; to render his anger with fierceness, and his rebuke with flames of fire.

I saw until thrones were placed, and one who was ancient of days sat: his clothing was white as snow, and the hair of his head like pure wool; his throne was fiery flames, [and] its wheels burning fire.
