And ye shall hallow the fiftieth year, and proclaim liberty throughout all the land unto all the inhabitants thereof: it shall be a jubile unto you; and ye shall return every man unto his possession, and ye shall return every man unto his family.
You must celebrate the 50th year and announce freedom for everyone in the land. This is called a "jubilee." During this time, each person should go back to their own property and be with their family.
