2 Kings 10:1

Ahab had seventy sons Grandsons are probably comprehended here under the name of sons, as is usual in the Scriptures: though, by several wives, he might have as many sons as Gideon had. These sons or grandsons were now in Samaria, either because they had been bred up there, that being the chief city of the kingdom; or because they had fled thither, upon receiving tidings of the slaughter of Joram; or had been conveyed thither, from different parts, by their friends, as to the strongest place. Here, as appears probable from Jehu's message, they intended to defend themselves and Ahab's children, and to set up one as king in Joram's stead. Jehu wrote letters unto the rulers of Jezreel Hebrew, the princes of Jezreel, that is, the great persons and officers of the court, which then was, and for some time had been, at Jezreel. These, it seems, had either fled to Samaria upon the news of Jehu's actions and successes, or had been sent thither by Joram with his sons, to take care of them there. To the elders Termed such from their age, or rather from their office, being the magistrates or senators of Samaria. And to them that brought up Ahab's children That had a more particular care of the several children under the inspection of the princes and elders here mentioned.
