I think he was suggesting that looking at a woman's body vs. her face is the difference between sexual lust and using a woman for pleasure vs. knowing a person by her face because it identifies her as a unique individual, and a daughter of God.

I don't think we can make a hard and fast rule over it, but by and large the face, and particularly the eyes, are "the windows to the soul", and is associated with reason and communication and higher senses.

The body is more associated with utility, and sensuality, and is more "primitive".

The face should be framed because one should be looking at a person as a person, and not as a means to an end (fulfillment of lust).

So I'd say that any Scripture that talks about selflessness, and modesty and self control, and taking every thought captive, and looking out for the interest of the other, and love for neighbor, etc.... would all apply here.
