For the potter, tempering soft earth, fashioneth every vessel with much labour for our service: yea, of the same clay he maketh both the vessels that serve for clean uses, and likewise also all such as serve to the contrary: but what is the use of either sort, the potter himself is the judge.
Consider the potter, who kneads soft clay and, with great effort, shapes every vessel for our use; from the very same clay he makes both the vessels meant for clean purposes and those meant for the opposite, and only the potter himself can say which is which.
