Matthew Poole and continuators on Acts 26:5

5 Which knew me from the beginning, (if they would testifie) that after the most straitest sect of our religion, I lived a Pharisee.

This Heresie, Sect, Opinion, or way of the Pharisees, St. Paul rightly commends, if we consider it comparatively with the other Sects of the Sadduces and Essenes; he had called this before, viz Chap. 22.3. the most exact manner of the Law of his Fathers: For it is certain it was more learned and strict, and came nigher to the Truth in many things than the other did.

Marginal references: Chap. 23.6. and 24.15. Phil. 3.5.
