The eye that mocks at his father, and despises to obey his mother, the ravens of the valley shall pick it out, and the young vultures shall eat it.
All Commentaries on Proverbs 30:17 Go To Proverbs 30
Hippolytus of Rome
AD 235
The eye that mocketh at his father, and dishonours the old age of his mother.” That is to say, one that blasphemes God and despises the mother of Christ, the wisdom of God,—his eyes may ravens from the caves tear out, i.e., him may unclean and wicked spirits deprive of the clear eye of gladness; and may the young eagles devour him: and such shall be trodden under the feet of the saints.
