Divrey Hayamim Bais 28:26-27

Orthodox Jewish Bible

²⁶ Now the rest of his acts and of all his ways, the rishonim and the acharonim, hinei, they are written in the Sefer of the Melachim of Yehudah and Yisroel.

²⁷ And Achaz slept with Avotav, and they buried him in the city, even in Yerushalayim, but they brought him not into the keverim of the Melachim of Yisroel. And Chizkiyah bno reigned in his place.
