Leviticus 25:8–17
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. / 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. / 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.
