'Eighty' in the Bible

and their brethren of all the families of Issachar are mighty of valour, eighty and seven thousand, all have their genealogy.

Of sons of Hebron: Eliel the chief, and his brethren, eighty.

And their number, with their brethren -- taught in the song of Jehovah, all who are intelligent -- is two hundred, eighty and eight.
