Ezekiel 39 (BSB)
⁶I will send fire on Magog and on those who dwell securely in the coastlands, and they will know that I am YHWH. ⁷So I will make My holy name known among My people Israel and will no longer allow it to be profaned. Then the nations will know that I am YHWH, the Holy One in Israel. ⁸Yes, it is coming, and it will surely happen, declares YHWH Elohim. This is the day of which I have spoken.

⁹Then those who dwell in the cities of Israel will go out, kindle fires, and burn up the weapons—the bucklers and shields, the bows and arrows, the clubs and spears. For seven years they will use them for fuel. ¹⁰They will not gather wood from the countryside or cut it from the forests, for they will use the weapons for fuel. They will loot those who looted them and plunder those who plundered them, declares YHWH Elohim.

¹¹And on that day I will give Gog a burial place in Israel, the Valley of the Travelers, east of the Sea. It will block those who travel through, because Gog and all his hordes will be buried there. So, it will be called the Valley of Hamon-gog. ¹²For seven months the house of Israel will be burying them in order to cleanse the land. ¹³All the people of the land will bury them, and it will bring them renown on the day I display My glory, declares YHWH Elohim.

¹⁴And men will be employed to continually pass through the land to cleanse it by burying the invaders who remain on the ground. At the end of the seven months they will begin their search. ¹⁵As they pass through the land, anyone who sees a human bone will set up a pillar next to it, until the gravediggers have buried it in the Valley of Hamon-gog. ¹⁶(Even the city will be named Hamonah.) And so, they will cleanse the land.

Revelation 11:18 (NKJV) The nations were angry, and Your wrath has come, And the time of the dead, that they should be judged, And that You should reward Your servants the prophets and the saints, And those who fear Your name, small and great, And should destroy those who destroy the earth.

Given the pollution, drugs, and damaging farming practices over the past three centuries, I would not be surprised if Yahshua makes us clean up the entire Earth for seventy years. Why?

Leviticus 25 (BSB)
¹Then YHWH said to Moses on Mount Sinai, ²“Speak to the Israelites and say to them: When you enter the land that I am giving you, the land itself must observe a Sabbath to YHWH.

³“For six years you may sow your field and prune your vineyard and gather its crops. ⁴But in the seventh year there shall be a Sabbath of complete rest for the land—a Sabbath to YHWH.

“You are not to sow your field or prune your vineyard. ⁵You are not to reap the aftergrowth of your harvest or gather the grapes of your untended vines. The land must have a year of complete rest. ⁶Whatever the land yields during the Sabbath year shall be food for you—for yourself, your manservant and maidservant, the hired hand or foreigner who stays with you, ⁷and for your livestock and the wild animals in your land. All its growth may serve as food.”

Leviticus 26 (BSB)
³⁴“Then the land shall enjoy its Sabbaths all the days it lies desolate, while you are in the land of your enemies. At that time the land will rest and enjoy its Sabbaths. ³⁵As long as it lies desolate, the land will have the rest it did not receive during the Sabbaths when you lived in it.”

2 Chronicles 36:21 So the land enjoyed its Sabbath rest all the days of the desolation, until seventy years were completed, in fulfillment of the word of YHWH through Jeremiah.

Some postulate that Israel had overworked the land, leaving little topsoil for crops; removing them could be seen as an act of mercy for the remnant since it can take up to a century for nature to renew its top layer for farming. Instead of kicking us out the land, as it was for Israel, the opposite is possible since we will be here for a thousand years [Revelation 20]. What else would we be doing as He establishes His reign on Earth? We helped create this disaster after all.
