A horse is a vain thing for safety: neither shall he deliver any by his great strength.
All Commentaries on Psalms 33:17 Go To Psalms 33
Augustine of Hippo
AD 430
17. "A horse is a deceitful thing for safety:" he is deceived, who thinketh either that through men he gaineth salvation received among men, or that by the impetuosity of his own courage he is defended from destruction. "In the abundance of his strength shall he not be saved" (ver. 17).
