The law of the Lord is perfect, reviving the soul; the decrees of the Lord are sure, making wise the simple, the precepts of the Lord are right, rejoicing the heart; the commandment of the Lord is clear, enlightening the eyes… (Psalm 19:7-8)
An overview of Ecclesiastes, Job, Psalms, Proverbs and Song of Solomon.
The sages had two sources of information about life: the natural world and their Wisdom tradition. Unlike prophets and priests, the sages believed that God wove important principles into the fabric of the universe, which careful observation could discern. The sages believed that things happen for reasons and that humans are able to figure out the workings of the universe. The prophets, in contrast, believed that God gives divine knowledge to select humans thorough dreams, visions, ecstasy, and divine appearance. Yet some of the sages felt outrage because their expectation was that the universe should make sense, but in their experience it did not. So these sages challenged the rationality of their universe and even the justice of God.
