Doesn't say a "whale" (whose gullet is the size of a softball, and is designed for eating plankton.) It says "a great fish." (Also, the "apple" is never mentioned as the "Fruit of the Tree of the Knowledge of Good and Evil.) ;) Actually it does say a whale:
Mat 12:40 For as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth.
