'Fiftieth' in the Bible

And ye shall hallow the fiftieth year, and proclaim liberty throughout the land unto all the inhabitants thereof: it shall be a jubilee unto you; and ye shall return every man unto his possession, and ye shall return every man unto his family.

A jubilee shall that fiftieth year be unto you: ye shall not sow, neither reap that which groweth of itself in it, nor gather the grapes in it of the undressed vines.
