Why did Philo Judaeus consider the Mosaic constitution an ideal form of government?

Philo Judaeus considered the Mosaic constitution to be the ideal form of government because he believed it successfully embodied the best elements of all political systems.1

For Philo, the concept of democracy was not defined by a specific structure of government, but rather by the presence of "due order" where all individuals are equal before the law. Because the Mosaic constitution achieves this state of equality while synthesizing the most virtuous aspects of various political forms, he viewed it as the ultimate model for society. Ultimately, Philo envisioned a future where the entire world would exist as a single state governed by such a democratic constitution.1
