'Deceit' in the Bible

And Jehoram turneth his hands, and fleeth, and saith unto Ahaziah, 'Deceit, O Ahaziah!'

Now send for all the prophets of Baal and all his servants and all his priests, to come to me; let no one keep away: for I have a great offering to make to Baal; anyone who is not present, will be put to death. This Jehu did with deceit, his purpose being the destruction of the servants of Baal.
