From the Fish mouth comes from the New Testament when Christ asks his disciple to take a coin from the fish mouth to pay taxes to Caesar. Thus we have the golden maxim: ‘give unto Caesar what is his and give unto me what is mine.’ As an idiom it means divine provision for one who is stricken with financial woes.
Example: I pray to Christ for granting me a coin from the fish mouth.
