Divrey Hayamim Bais 22:9

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).

Divrey Hayamim Bais 22:9 Meaning and Commentary

Ver. 9-11. And he sought Ahaziah
Who fled on Joram's being wounded by Jehu:

and they caught him;
the soldiers of Jehu, who were sent after him, and bid to smite him:

for he was hid in Samaria;
either in some part of the kingdom of Samaria, or in the city itself, whither he fled:

and brought him to Jehu:
who was at Jezreel, (See Gill on 2 Kings 9:27),

and when they had slain him they buried him;
not at Jezreel, but delivered him to his servants to carry him to Jerusalem, and there bury him in the sepulchres of his fathers, ( 2 Kings 9:28 ) ,

because, said they, he is the son of Jehoshaphat, who sought the Lord
with all his heart;
a grandson of his, and therefore out of respect to the memory of his name, these being religious men, ordered his burial there:

so the house of Ahaziah had no power to keep still the kingdom;
his brethren and their sons being slain, and his own children being young fell into the hands of Athaliah, who murdered them all, but one, hid by his aunt, and so got the government into her own hands, as may be observed in the following verses, ( 2 Chronicles 22:10-12 ) .

Divrey Hayamim Bais 22:9 In-Context

7 And the tevusat Achazyahu (downfall of Ahaziah) was of Elohim in coming to Yoram, for when he arrived, he went out with Yehoram against Yehu ben Nimshi, whom Hashem had anointed to cut off the Bais Ach’av (the House of Ahab).

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.

11 But Yehoshavat Bat HaMelech, took Yoash ben Achazyahu, and stole him away from among the Bnei HaMelech that were being murdered, and put him and his nurse in a cheder hamittot (bedroom). So Yehoshavat Bat HaMelech Yehoram, the isha of Yehoyada HaKohen, (for she was the achot of Achazyahu), hid him from Atalyah, so that she slaughtered him not.
