Task of Beirurim

Tree of the knowledge of good and evil.

In the Kabbalah, the sin of the Tree of Knowledge (called Cheit Eitz HaDa’at) brought about the great task of beirurim, sifting through the mixture of good and evil in the world to extract and liberate the sparks of holiness trapped therein.
