'Fiftieth' in the Bible

Sound a horn on the tenth day of the seventh month of this fiftieth year. Likewise, on the Day of Atonement, sound the horn throughout your land.

Set aside and consecrate the fiftieth year to declare liberty throughout the land for all of its inhabitants. It is to be a jubilee for you. Every person is to return to his own land that he has inherited. Likewise, every person is to return to his tribe.

The fiftieth year is to be a year of jubilee for you. You are not to sow or harvest the spilled kernels that grow of themselves or pick grapes from the untrimmed vines
