2 Chronicles 35:24-25

24So his servants took him out of the chariot and carried him on the second chariot which he had, and brought him to Jerusalem 1where he died and was buried in the tombs of his fathers. 2All Judah and Jerusalem mourned for Josiah.

25Then 3Jeremiah 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.
