'Eighty' in the Bible

There was a great famine in Samaria, and behold, a siege [was] against it, until the head of a donkey [went] for eighty shekels of silver, and one fourth of the measure of the dung of doves [went] for five shekels of silver.

They came to offer sacrifices and burnt offerings. Now Jehu had stationed for himself eighty men outside, and he said, "The man who lets [anyone] escape from the men who I am {entrusting to you}, {he will pay with his life}!"
