Israelites had what was called the year of Jubilee every 49 years. During this year people would return to their ancestors home land and would grow no crops. God would provide enough yield for the upcoming year of Jubilee.

1. All slaves would be freed
2. Property that was sold would be returned to the family that originally owned it
3. And there would be no agriculture

The purpose of this year was to make sure that people relied on God instead of gaining great power from earthly possessions. It also made sure that those who had been successful didn’t build large amounts of wealth at the expense of the less fortunate.
