Divrey Hayamim Bais 25:25-27

Orthodox Jewish Bible

²⁵ And Amatzyahu ben Yoash Melech Yehudah lived after the mot Yoash ben Yehoachaz Melech Yisroel fifteen years.

²⁶ Now the rest of the acts of Amatzyahu, harishonim and ha’acharonim, hinei, are they not written in the Sefer of the Melachim of Yehudah and Yisroel?

²⁷ Now after the time that Amatzyah did turn away from following Hashem they made a kesher against him in Yerushalayim; and he fled to Lachish, but they sent to Lachish after him, and slaughtered him there.
