And all the mountain of Sinai was smoking, for the Lord had come down on it in fire: and the smoke of it went up like the smoke of a great burning; and all the mountain was shaking.
And the angel of the Lord was seen by him in a flame of fire coming out of a thorn-tree: and he saw that the tree was on fire, but it was not burned up.
And I saw it coloured like electrum, with the look of fire in it and round it, going up from what seemed to be the middle of his body; and going down from what seemed to be the middle of his body I saw what was like fire, and there was a bright light shining round him.
Like the bow in the cloud on a day of rain, so was the light shining round him. And this is what the glory of the Lord was like. And when I saw it I went down on my face, and the voice of one talking came to my ears.
Who may keep his place before his wrath? and who may undergo the heat of his passion? his wrath is let loose like fire and the rocks are broken open by him.
Out of heaven itself his voice came to you, teaching you; and on earth he let you see his great fire; and his words came to your ears out of the heart of the fire.
Be certain then today that it is the Lord your God who goes over before you like an all-burning fire; he will send destruction on them, crushing them before you; and you will send them in flight, putting an end to them quickly, as the Lord has said.
