2 Chronicles 35:24-25

24So his servants carried him out of the chariot and put him in the second chariot that he had. They brought him to Jerusalem where he died and was buried in the tombs of his fathers. All Judah and Jerusalem mourned over Josiah.

25Now Jeremiah composed laments for Josiah, and to this day all the singers, male and female, commemorated Josiah in their laments. And they made them an ordinance in Israel and behold, they are written in the lamentations.
