Leviticus 25:8-15

“In addition, you must count off seven Sabbath years, seven sets of seven years, adding up to forty-nine years in all. Then on the Day of Atonement in the fiftieth year, blow the ram’s horn loud and long throughout the land. Set this year apart as holy, a time to proclaim freedom throughout the land for all who live there. It will be a jubilee year for you, when each of you may return to the land that belonged to your ancestors and return to your own clan. This fiftieth year will be a jubilee for you. During that year you must not plant your fields or store away any of the crops that grow on their own, and don’t gather the grapes from your unpruned vines. It will be a jubilee year for you, and you must keep it holy. But you may eat whatever the land produces on its own. In the Year of Jubilee each of you may return to the land that belonged to your ancestors. “When you make an agreement with your neighbor to buy or sell property, you must not take advantage of each other. When you buy land from your neighbor, the price you pay must be based on the number of years since the last jubilee. The seller must set the price by taking into account the number of years remaining until the next Year of Jubilee.
