Charles Ellicott Commentary 2 Chronicles 22:10

"Now when Athaliah the mother of Ahaziah saw that her son was dead, she arose and destroyed all the seed royal of the house of Judah." — 2 Chronicles 22:10 (ASV)

ATHALIAH SEIZES THE GOVERNMENT (2 Chronicles 22:10–12). (Compare to 2 Kings 11:1–3).

But when Athaliah. —See 2 Kings 11:1, with which this verse nearly coincides.

Destroyed. —So Kings and some Hebrew MSS., and all the versions. Hebrew text, she spoke, a mistake of some scribe.

All the seed royal. —Even after the massacres described in 2 Chronicles 22:1; 2 Chronicles 22:8, there would doubtless be left a number of persons more or less nearly connected with the royal family, besides the immediate offspring of Ahaziah, who are, in the first instance, intended by this phrase.
