What did god want the fish to do?

This question requires more context! "God" can refer to many different deities in different religions and myths.

To give you a helpful answer, I need more information. For example:

* Which god are you referring to? The god of the Bible, a specific deity from another religion, or a mythical god from a story?

* What story are you thinking of? Is there a specific story or passage where a god interacts with a fish?

* What is the context? What is the fish doing? What is the situation surrounding this interaction?

Please provide more details so I can understand what you are asking!
