But there were also false prophets in Israel, just as there will be false teachers among you. They will cleverly teach destructive heresies and even deny the Master who bought them. In this way, they will bring sudden destruction on themselves. Many will follow their evil teaching and shameful immorality. And because of these teachers, the way of truth will be slandered. In their greed they will make up clever lies to get hold of your money. But God condemned them long ago, and their destruction will not be delayed.
2 Peter 2:1-3
