'Three score' in the Bible

and this whole land shall become a wilderness, and they shall serve the said people and the king of Babylon, three score years and ten.

He took also out of the city an eunuch, which had the charge of the men of war; and seven men of them that were near the king's person, which were found in the city; and the principal scribe of the host, who mustered the people of the land; and threescore men of the people of the land, that were found in the midst of the city.
