What does the Bible say about the Pharisees and Sadducees?

In Matthew 16:1-12, the Pharisees and Sadducees come together to test Jesus, showcasing their opposition to Him despite their usual enmity towards one another. The Pharisees are often characterized as self-righteous formalists who cling to strict interpretations of the Law, while the Sadducees, in contrast, are skeptics and freethinkers, often rejecting the resurrection and the supernatural. This union in opposition to the Gospel highlights how individuals from differing backgrounds can unite in their rejection of Christ's message.
