2 Kings 10:12-14

And he arose, and came to Samaria Having finished his work in Jezreel, he went to prosecute it in the chief city of his kingdom, which most needed reformation. Jehu met the brethren of Ahaziah Not strictly such; for his brethren, properly speaking, had been carried captive, and, it seems, killed also, before this time, as we read 2 Chronicles 21:17. Therefore, by brethren here, we must understand his brother's sons, as is explained 2 Chronicles 22:8, or others of his near kinsmen, such being often called brethren in Scripture. We go down to salute the children of the king, &c. They undoubtedly had set out from Jerusalem for this purpose, before they knew any thing of Joram's being killed, and Jehu's having seized the kingdom: and it appears by their answer, that they did not yet know any thing of it. And he said, Take them alive, &c. They were allied to the family of Ahab by the mother's side, (2 Kings 8:18,) and therefore being afraid lest, if they were suffered to live, they might find means to be avenged of him for the death of Joram, Ahaziah, Jezebel, and their children, whom they were going to visit, he ordered them to be slain; perhaps under pretence of fulfilling Elijah's prophecy, 1 Kings 21:21. It seems, however, evident, that prediction did not extend so far, but would have been amply fulfilled by cutting off all of his family and blood within the kingdom of the ten tribes.
