2 Chronicles 35:24-25

24So his servants took him out of the chariot and carried him in the second chariot which he had, and brought him to Jerusalem where he died and was buried in the tombs of his fathers. All Judah and Jerusalem mourned for Josiah.

25Then Jeremiah sung a lament (funeral song) for Josiah, and all the male and female singers have spoken about Josiah in their laments to this day. They made the songs an ordinance in Israel; behold, they are written in the Lamentations.
