Leviticus 25:12-22

12 The whole year shall be sacred for you; you shall eat only what the fields produce of themselves.
13 In this year all property that has been sold shall be restored to its original owner.
14 So when you sell land to an Israelite or buy land, do not deal unfairly.
15 The price is to be set according to the number of years the land can produce crops before the next Year of Restoration.
16 If there are many years, the price shall be higher, but if there are only a few years, the price shall be lower, because what is being sold is the number of crops the land can produce.
17 Do not cheat an Israelite, but obey the Lord your God.
18 Obey all the Lord's laws and commands, so that you may live in safety in the land.
19 The land will produce its crops, and you will have all you want to eat and will live in safety.
20 But someone may ask what there will be to eat during the seventh year, when no fields are planted and no crops gathered.
21 The Lord will bless the land in the sixth year so that it will produce enough food for two years.
22 When you plant your fields in the eighth year, you will still be eating what you harvested during the sixth year, and you will have enough to eat until the crops you plant that year are harvested.
