Divrey Hayamim Bais 22:8 Meaning and Commentary

2 Chronicles 22:8

And it came to pass, that when Jehu was executing judgment on
the house of Ahab
On Joram, his son, and seventy more sons, his kinsfolks, courtiers, and priests:

and found the princes of Judah, and or even the sons of the brethren of
Ahaziah;
whose number was forty two:

that ministered to Ahaziah;
had offices in his court, or in obedience to his will, went to visit the children of the king and queen of Israel:

and he slew them;
Jehu did; of the occasion, time, and place of his meeting with them, and slaying them, see ( 2 Kings 10:12-14 ) .

Divrey Hayamim Bais 22:8 In-Context

6 And he (Yoram) returned to Yizre’el (Jezreel) to recover from his wounds which were inflicted upon him at Ramah, when he fought with Chatzael Melech Aram. And Achazyahu (Ahaziah) ben Yehoram Melech Yehudah went down to see Yehoram ben Ach’av at Yizre’el (Jezreel), because he was wounded.

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.
