'Fiftieth' in the Bible

You shall make the fiftieth year holy, and proclaim liberty throughout the land to all its inhabitants. It shall be a jubilee to you; and each of you shall return to his own property, and each of you shall return to his family.

That fiftieth year shall be a jubilee to you. In it you shall not sow, neither reap that which grows of itself, nor gather from the undressed vines.
