Who is as the wise man? and who knows the interpretation of a thing? a man's wisdom makes his face to shine, and the hardness of his face is changed.
All Commentaries on Ecclesiastes 8:1 Go To Ecclesiastes 8
Didymus the Blind
AD 398
Here he means that the wisdom of a person makes the face shine, but not the face of the body, not a part of the flesh, but the face of the inner person.… The face of the inner person is illuminated by wisdom. But wisdom, light, Logos, truth and the other conceptions are identical when applied to Christ.
