And mount Sinai was completely in smoke, because the LORD descended upon it in fire: and the smoke of it ascended as the smoke of a furnace, and the whole mount quaked greatly.
And the angel of the LORD appeared unto him in a flame of fire out of the midst of a bush: and he looked, and, behold, the bush burned with fire, and the bush was not consumed.
And I saw as the color of amber, as the appearance of fire round about within it, from the appearance of his waist even upward, and from the appearance of his waist even downward, I saw as it were the appearance of fire, and it had brightness round about.
As the appearance of the bow that is in the cloud in the day of rain, so was the appearance of the brightness round about. This was the appearance of the likeness of the glory of the LORD. And when I saw it, I fell upon my face, and I heard a voice of one that spoke.
Who can stand before his indignation? and who can abide in the fierceness of his anger? his fury is poured out like fire, and the rocks are thrown down by him.
Out of heaven he made you to hear his voice, that he might instruct you: and upon earth he showed you his great fire; and you heard his words out of the midst of the fire.
Understand therefore this day, that the LORD your God is he who goes over before you; as a consuming fire he shall destroy them, and he shall bring them down before your face: so shall you drive them out, and destroy them quickly, as the LORD has said unto you.
