Yirmeyah 36:7-9

Orthodox Jewish Bible

⁷ It may be they will present their techinnah (supplication) before Hashem, and they will turn every ish from his derech hara’ah; for gadol is the anger and the wrath that Hashem hath pronounced against HaAm Hazeh.

⁸ And Baruch Ben Neriyah did according to all that Yirmeyah HaNavi commanded him, reading the Sefer Divrei Hashem in the Bais Hashem.

⁹ And it came to pass in the fifth year of Y’hoyakim Ben Yoshiyah Melech Yehudah, in the ninth month, that they proclaimed a tzom before Hashem to kol HaAm in Yerushalayim, and to kol HaAm that came from the towns of Yehudah unto Yerushalayim.
