Leviticus 25:8-12

8“ ‘Count off seven sabbath years—seven times seven years—so that the seven sabbath years amount to a period of forty-nine years.

9Then have the trumpet sounded everywhere on the tenth day of the seventh month; on the Day of Atonement sound the trumpet throughout your land.

10Consecrate the fiftieth year and proclaim liberty throughout the land to all its inhabitants. It shall be a jubilee for you; each of you is to return to your family property and to your own clan.

11The fiftieth year shall be a jubilee for you; do not sow and do not reap what grows of itself or harvest the untended vines.

12For it is a jubilee and is to be holy for you; eat only what is taken directly from the fields.
