Divrey Hayamim Bais 22:8-10

Orthodox Jewish Bible

⁸ And it came to pass, that, when Yehu was executing mishpat upon the Bais Ach’av, and found the sarei Yehudah, and the bnei achei Achazyahu that were in attendance with Achazyahu, he slaughtered them.

⁹ And he searched for Achazyahu, and they captured him while he was hiding in Shomron (Samaria), and brought him to Yehu; and when they had slain him, they buried him. Because, they said, he is a ben Yehoshaphat, who sought Hashem with all his levav. So the Bais Achazyahu had no koach to retain the mamlachah (kingdom).

¹⁰ But when Atalyah em Achazyahu saw that her son was dead, she arose and began destroying kol zera hamamlachah (all the royal seed) of the Bais Yehudah.
