'Eighty' in the Bible

And there was a great famine in Samaria; and behold, they besieged it, until an ass's head was worth eighty silver-pieces, and the fourth part of a cab of dove's dung five silver-pieces.

And they entered in to offer sacrifices and burnt-offerings. Now Jehu appointed eighty men without, and said, He that allows any of the men to escape that I have brought into your hands, his life shall be for the life of him.
