Exod 25:20 · Douay-Rheims
“Let them cover both sides of the propitiatory, spreading their wings, and covering the oracle, and let them look one towards the other, their faces being turned towards the propitiatory wherewith the ark is to be covered.”

“As a sign of Him, there are the two Cherubim turned toward each other, but with their faces looking toward the propitiatory. The two Cherubim are the two Testaments whose gaze is directed upon Christ. He opened their minds when they understood the Scriptures, meaning that the book of Scriptures is understood precisely through that key, the Incarnate Word, the one eminently concerned with the works of restoration. For unless you understand the order and origin of restoration, you cannot understand Scriptures.”

“For the Cherubim also designate this, who looked upon one another. Nor is it without mystery that they looked upon one another with their faces turned toward the mercy seat, so that what the Lord says in John may be verified: "This is eternal life, that they may know thee, the only true God, and Jesus Christ whom thou hast sent." For we ought to admire not only the essential and personal conditions of God in themselves, but also by comparison to the superadmirable union of God and man in the unity of the person of Christ.”
