2 Chronicles 35:24-27

35:24 So his servants took him out of the chariot, put him in another chariot that he owned, and brought him to Jerusalem, where he died. He was buried in the tombs of his ancestors; all the people of Judah and Jerusalem mourned Josiah. 35:25 Jeremiah composed laments for Josiah which all the male and female singers use to mourn Josiah to this very day. It has become customary in Israel to sing these; they are recorded in the Book of Laments.

35:26 The rest of the events of Josiah’s reign, including the faithful acts he did in obedience to what is written in the law of the Lord 35:27 and his accomplishments, from start to finish, are recorded in the Scroll of the Kings of Israel and Judah.
