'Day' in the Bible

Who can endure the day of his coming? Who can keep standing when he appears? For he will be like a refiner's fire, like a launderer's soap.

"They will belong to me," says the Lord who rules over all, "in the day when I prepare my own special property. I will spare them as a man spares his son who serves him.

"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.

You will trample on the wicked, for they will be like ashes under the soles of your feet on the day which I am preparing," says the Lord who rules over all.

Look, I will send you Elijah the prophet before the great and terrible day of the Lord arrives.
