'Party' in the Bible

Now the high priest rose up, and all those with him (that is, the religious party of the Sadducees), and they were filled with jealousy.

But some from the religious party of the Pharisees who had believed stood up and said, "It is necessary to circumcise the Gentiles and to order them to observe the law of Moses."

There was a great commotion, and some experts in the law from the party of the Pharisees stood up and protested strongly, "We find nothing wrong with this man. What if a spirit or an angel has spoken to him?"

They know, because they have known me from time past, if they are willing to testify, that according to the strictest party of our religion, I lived as a Pharisee.
