Levítico 26

Levítico 26:10

For just as the teachings of the new and old Testaments should come together, as it is written: "Consume the old things of the ancients, and remove the old things from the face of the new ones." Let the knowledge of the patriarchs be food for us, let the soul feast on the oracles of the prophets: let the inner being be nourished by such sustenance. But now let it not be the appearance of a lamb, but rather the reality of the body of Christ. Let it not be the shadow of the law that blinds the eyes, but rather let the grace of the Lord's passion openly reveal, and let the splendor of the resurrection illuminate the mind's sight. — On Cain and Abel 2.6.19
