but the seventh year you must let your fields and vineyards rest in honour of me, your LORD.
Judah was an empty desert, and it stayed that way for seventy years, to make up for all the years it was not allowed to rest. These things happened just as Jeremiah the LORD's prophet had said.
This is to be a time of complete rest for your fields and vineyards, so don't harvest anything they produce.
and let it rest during the time that you are in a foreign country, paying for your rebellion against me and my laws.
