John the Baptist and the Pharisees and the Sadducees

John the Baptist is also going to be confronted by the Pharisees and the Sadducees. He calls them a brood of vipers, right? And Jesus is going to use the exact same phrase later in the gospel. This sets up a major motif. The leaders, the kings and the leaders who are able to arrest Jesus for example. These are blind guides. What happens when you have a blind guide? You end up in a pit.
