Leviticus 25:8-11

The Year of Jubilee
“‘Count off seven sabbaths of years—seven times seven years—so that the seven sabbaths of years amount to a period of forty-nine years.
9 Then have the trumpet sounded everywhere on the tenth day of the seventh month; on the Day of Atonement sound the trumpet throughout your land.
10 Consecrate the fiftieth year and proclaim liberty throughout the land to all its inhabitants. It shall be a jubilee for you; each one of you is to return to his family property and each to his own clan.
11 The fiftieth year shall be a jubilee for you; do not sow and do not reap what grows of itself or harvest the untended vines.
