'Twenty third' in the Bible

From the thirteenth year of Josiah the son of Amon king of Judah, even to this day, that is the twenty-third year, the Word of Jehovah has come to me, and I have spoken to you, rising early and speaking. But you have not listened.

in Nebuchadnezzar's twenty-third year, Nebuzaradan the captain of the guard took 745 people from Judah into exile. All the people taken into exile numbered 4,600.
