Question: Can someone cite lines from the Torah that specify what Jews should eat during Passover? I'm aware that Jews don't eat leavened bread during Passover. Where does this rule come from?

Answer: 
From the [Wikipedia article](http://en.wikipedia.org/wiki/Chametz#Torah_related_sources) on Chametz (leaven):

> 
> The Torah has several commandments governing chametz during Passover:
> 
> 
> * The positive commandment to remove all chametz from one's home ([Exodus 12:15](http://bibref.hebtools.com/?book=%20Exodus&verse=12:15&src=HE)).
> * Not to possess chametz in one's domain. ([Exodus 12:19](http://bibref.hebtools.com/?book=%20Exodus&verse=12:19&src=HE), [Deuteronomy 16:4](http://bibref.hebtools.com/?book=%20Deuteronomy&verse=16:4&src=HE)).
> * Not to eat chametz, or mixtures containing chametz ([Exodus 13:3](http://bibref.hebtools.com/?book=%20Exodus&verse=13:3&src=HE), [Exodus 12:20](http://bibref.hebtools.com/?book=%20Exodus&verse=12:20&src=HE), [Deuteronomy 16:3](http://bibref.hebtools.com/?book=%20Deuteronomy&verse=16:3&src=HE)).

It's in the book of [Shemos (Exodus), 12:18-19](http://mechon-mamre.org/p/pt/pt0212.htm)
