Leviticus 25:8-12

8“You are to count seven sabbatical years, seven times seven years, so that the time period of the seven sabbatical years amounts to forty-nine.

9Then you are to sound a ram’s horn loudly in the seventh month, on the tenth day of the month; you will sound it throughout your land on the Day of Atonement.

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

11The fiftieth year will be your Jubilee; you are not to sow, reap what grows by itself, or harvest its untended vines.

12It is to be holy to you because it is the Jubilee; you may only eat its produce directly from the field.
