'Fiftieth' in the Bible

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.

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.
