2 Chronicles 35:25-29

Then Jeremiah chanted a song of mourning for Josiah. And all the male and female singers speak about Josiah in their songs of mourning to this day. And they made them an ordinance in Israel; behold, they are also written in the Lamentations.

Now the rest of the acts of Josiah and his deeds of devotion as written in the Law of the Lord,

and his acts, the first to the last, behold, they are written in the Book of the Kings of Israel and Judah.
