Leviticus 25
8 Ref And let seven Sabbaths of years be numbered to you, seven times seven years; even the days of seven Sabbaths of years, that is forty-nine years;
9 Ref Then let the loud horn be sounded far and wide on the tenth day of the seventh month; on the day of taking away sin let the horn be sounded through all your land.
10 Ref And let this fiftieth year be kept holy, and say publicly that everyone in the land is free from debt: it is the Jubilee, and every man may go back to his heritage and to his family.
11 Ref Let this fiftieth year be the Jubilee: no seed may be planted, and that which comes to growth of itself may not be cut, and the grapes may not be taken from the uncared-for vines.
