Y los encantadores hicieron así también, para sacar piojos con sus encantamientos; mas no pudieron. Y había piojos así en los hombres como en las bestias.
On the Migration of Abraham
[85] Accordingly “Aaron’s rod swallowed up their rods” (Ex. 7:12), as the oracle shews. For all the arguments of sophists are devoured and done away with by Nature’s many-sided skill, and the acknowledgement is made that these events are the Finger of God (Ex. 8:19), and the word “Finger” is equivalent to a divine rescript, declaring that sophistry is ever defeated by wisdom; for holy writ, speaking of the tables on which the oracles were engraved, says that they were written by the Finger of God (Ex. 32:16). Wherefore the sorcerers can no longer stand before Moses, but fall as in a wrestling-bout vanquished by the sturdy strength of the opponent (Ex. 8:18).
