2 Kings 9:18-20
9:18 So the horseman went to meet him and said, “This is what the king says, ‘Is everything all right?’” Jehu replied, “None of your business! Follow me.” The watchman reported, “The messenger reached them, but hasn’t started back.”
9:19 So he sent a second horseman out to them and he said, “This is what the king says, ‘Is everything all right?’” Jehu replied, “None of your business! Follow me.”
9:20 The watchman reported, “He reached them, but hasn’t started back. The one who drives the lead chariot drives like Jehu son of Nimshi; he drives recklessly.”
