Isaiah 24:3-5.”The land shall be utterly emptied, and utterly spoiled; for the Lord hath spoken this word. The earth mourneth and fadeth away, the world languisheth and fadeth away, the haughty people of the earth do languish. The earth also is defiled under the inhabitants thereof; because they have transgressed the laws, changed the ordinance, broken the everlasting covenant.”
Sometimes, the word earth should be taken as land, referencing Israel. It is Israel that has broken the covenant in Genesis 9:16. The covenant, a Divine promise, was forsaken over and over again by Israel down through the centuries.
As to the future, the agreement which the apostate nation (the godly remnant excluded) will make with the Man of Sin, will absolutely fulfill all that is stated in verse 5.
Starting in verse six, we will see the judgments that will depopulate the earth.
