Leviticus 25:12

8 And you shall count off seven Sabbaths of years—seven times seven years—so that the seven Sabbaths of years amount to forty-nine years.

9 Then you are to sound the horn far and wide on the tenth day of the seventh month, the Day of Atonement. You shall sound it throughout your land.

10 So you are to consecrate the fiftieth year and proclaim liberty in the land for all its inhabitants. It shall be your Jubilee, when each of you is to return to his property and to his clan.

11 The fiftieth year will be a Jubilee for you; you are not to sow the land or reap its aftergrowth or harvest the untended vines.

12 For it is a Jubilee; it shall be holy to you. You may eat only the crops taken directly from the field.

13 In this Year of Jubilee, each of you shall return to his own property.

14 If you make a sale to your neighbor or a purchase from him, you must not take advantage of each other.

15 You are to buy from your neighbor according to the number of years since the last Jubilee; he is to sell to you according to the number of harvest years remaining.

16 You shall increase the price in proportion to a greater number of years, or decrease it in proportion to a lesser number of years; for he is selling you a given number of harvests.
