'Thirteenth' in the Bible

To whom the word of the Lord came in the days of Josiah, the son of Amon, king of Judah, in the thirteenth year of his rule.

From the thirteenth year of Josiah, the son of Amon, king of Judah, even till this day, for twenty-three years, the word of the Lord has been coming to me, and I have given it to you, getting up early and talking to you; but you have not given ear.
