De Virtutibus

for indeed the mightiest monarch appears poor and helpless if he is put in comparison with one single virtue, for he has only inanimate riches buried in his treasuries or in the recesses of the earth, but the wealth of virtue is stored up in the dominant part of the soul; and that purest of all essences, heaven, claims itself a share in that, as likewise does the Creator and Father of the universe, God. Therefore we must look upon and denominate the opulence of money-changers and usurers as poverty, though they appear to themselves to be mighty kings, while they have never beheld that wealth which is really endowed with sight, no not even in their dreams.

And these men run into such extravagances of wickedness, that if they have not money, they make usurious advances even of food, lending it on condition of receiving back again more than they lent. Accordingly, such men will speedily afford a contribution to those who ask for one, preparing famine and scarcity against a time of plenty and abundance, and making a revenue of the hunger of the bellies of miserable men, weighing out the food as it were in a scale, and taking care not to give overweight.

Therefore he necessarily commands those who live under his sacred constitution to avoid every description of revenues of this kind, for all such pursuits were the sign of a thoroughly slavish and illiberal mind, which must be changed into savageness and into the resemblance of brute beasts, before it could adopt them.
