'Fiftieth' in the Bible

So you must consecrate the fiftieth year, and you must proclaim a release in the land for all its inhabitants. That year will be your jubilee; each one of you must return to his property and each one of you must return to his clan.

That fiftieth year will be your jubilee; you must not sow the land, harvest its aftergrowth, or pick the grapes of its unpruned vines.

In the fiftieth year of King Azariah's reign over Judah, Menahem's son Pekahiah became king over Israel. He reigned in Samaria for two years.
