Leviticus 25:10-17 NCV

10 Make the fiftieth year a special year, and announce freedom for all the people living in your country. This time will be called Jubilee. You will each go back to your own property, each to your own family and family group.
11 The fiftieth year will be a special time for you to celebrate. Don't plant seeds, or harvest the crops that grow by themselves, or gather grapes from the vines that are not trimmed.
12 That year is Jubilee; it will be a holy time for you. You may eat only the crops that come from the field.
13 In the year of Jubilee you each must go back to your own property.
14 "'If you sell your land to your neighbor, or if you buy land from your neighbor, don't cheat each other.
15 If you want to buy your neighbor's land, count the number of years since the last Jubilee, and use that number to decide the right price. If your neighbor sells the land to you, count the number of years left for harvesting crops, and use that number to decide the right price.
16 If there are many years, the price will be high. But if there are only a few years, lower the price, because your neighbor is really selling only a few crops to you.
17 You must not cheat each other, but you must respect your God. I am the Lord your God.
