How did Neo-Pythagorean ideas about numbers influence Philo Judaeus?

Philo Judaeus was significantly influenced by Neo-Pythagoreanism, particularly regarding the mystical significance of numbers. He placed special emphasis on the number seven, viewing it as having profound symbolic meaning.1

Beyond numerical mysticism, Philo adopted the Neo-Pythagorean concept of a self-disciplined way of life, which he viewed as essential preparation for achieving immortality. While Philo integrated these ideas into his broader philosophical framework—which was primarily Platonic—his engagement with Neo-Pythagorean thought helped shape his unique approach to ethics and his efforts to present Judaism as a profound, mystery-oriented tradition.1
