Yirmeyah 36:21-23

Orthodox Jewish Bible

²¹ So HaMelech sent Yehudi to bring the megilah; and he brought it out the lishka of Elishama the sofer. And Yehudi read it in the oznayim of HaMelech, and in the oznayim of all the sarim which Tzidkiyah Ben Chananyahu, and all stood beside HaMelech.

²² Now HaMelech sat in the Bais Hakhoref (Winter House) in the ninth month [Kislev]; and there was an akh (fireplace) burning before him.

²³ And it came to pass, that when Yehudi had read three or four delatot (columns), he cut it with a ta’ar hasofer (razor of a scribe), and cast it into the eish that was in the akh (fireplace), until all the megilah was consumed in the eish that was in the akh (fireplace).
