12.  The Stater Allegorized.

But you might sometimes gracefully apply the passage to the lover of money, who has nothing in his mouth but things about silver, when you behold him healed by some Peter, who takes the stater, which is the symbol of all his avarice, not only from his mouth and words, but from his whole character.  For you will say that such an one was in the sea, and in the bitter affairs of life, and in the waves of the cares and anxieties of avarice, having the stater in his mouth when he was unbelieving and avaricious, but that he came up from the sea and was caught in the rational net, and being benefited by some Peter who has taught him the truth, no longer has the stater in his mouth, but in place of it those things which contain His image, the oracles of God.
