Ecclesiaste 7:19

Wisdom strengtheneth the wise more than ten mighty men which are in the city. Wisdom strengtheneth the wise - One wise, thoroughly learned, and scientific man, may be of more use in fortifying and defending a city, than ten princes. Witness the case of Syracuse, when attacked by the Romans both by sea and land. Archimedes, by his engines, burnt and dashed their fleet to pieces, and destroyed all that came near the walls. And had not the city been betrayed and he killed, all their force and skill could not have taken it.
