'Eighty' in the Bible

There was a great famine in Samaria; and behold, they besieged it, until a donkey’s head was sold for eighty shekels of silver, and a fourth of a kab of dove’s dung for five shekels of silver.

Then they went in to offer sacrifices and burnt offerings.Now Jehu had stationed for himself eighty men outside, and he had said, “The one who permits any of the men whom I bring into your hands to escape shall give up his life in exchange.”
