Surely the serpent will bite without enchantment; and a babbler is no better.
All Commentaries on Ecclesiastes 10:11 Go To Ecclesiastes 10
Didymus the Blind
AD 398
The snake is powerful, when it spreads its poison secretly. In the one who is tricked, an impression is created that he has received something good which in reality is not good. The teacher who charms should not do so in a superflous way but in a way that accomplishes something. Then he shows his [student] the error, the guile of his seducer.
