2 Kings 10:9

Ye be righteous. The men of Jezreel were innocent of slaying any of the seed of Ahab, and Jehu publicly pronounced them so. He frankly confessed that it was he who had conspired against his master the king and had put him to death. But he also wanted to make it clear that he was not alone in what was going on — all he had done was to start something in which many were now having part. While Jehu was at Jezreel the leading men of Samaria had put to death all the royal seed; hence they were now participants with him in the move to rid the land of all the family of Ahab.
