Now Mount Sinai was completely covered with smoke because the Lord had descended on it in fire, and its smoke went up like the smoke of a great furnace, and the whole mountain shook violently.
As I watched, I noticed a windstorm coming from the north – an enormous cloud, with lightning flashing, such that bright light rimmed it and came from it like glowing amber from the middle of a fire.
A river of fire was streaming forth and proceeding from his presence. Many thousands were ministering to him; Many tens of thousands stood ready to serve him. The court convened and the books were opened.
(3:19) “For indeed the day is coming, burning like a furnace, and all the arrogant evildoers will be chaff. The coming day will burn them up,” says the Lord who rules over all. “It will not leave even a root or branch.
His winnowing fork is in his hand, and he will clean out his threshing floor and will gather his wheat into the storehouse, but the chaff he will burn up with inextinguishable fire.”
Understand today that the Lord your God who goes before you is a devouring fire; he will defeat and subdue them before you. You will dispossess and destroy them quickly just as he has told you.
