Charles Ellicott Commentary 2 Kings 10:13

"Jehu met with the brethren of Ahaziah king of Judah, and said, Who are ye? And they answered, We are the brethren of Ahaziah: and we go down to salute the children of the king and the children of the queen." — 2 Kings 10:13 (ASV)

Jehu met with. —Literally, And Jehu found.

The brethren of Ahaziah king of Judah — that is, Ahaziah’s kinsmen. His brothers, in the strict sense of the word, were killed by a troop of Arabs in the lifetime of his father Jehoram (2 Chronicles 21:17; 2 Chronicles 22:1). (See the Notes on 2 Chronicles 22:8.)

We go down. —Rather, we have come down.

To salute — that is, to inquire after their health, to visit them.

The children of the king — that is, the sons of Joram.

The children of the queen. —Literally, the sons of the mistress (gebîrah) —that is, the sons of the queen-mother, Jezebel, and so Joram’s brothers. Both these and the former are included in the sons of Ahab whom Jehu killed.

The news of the taking of Ramoth, and of Joram’s convalescence, may have reached Jerusalem, and induced these princes to make a visit of pleasure to the court of Jezreel, not suspecting the events which had meanwhile happened with the headlong rapidity characteristic of Jehu’s action.
