申命記 16:3

你吃這祭牲，不可吃有酵的餅；七日之內要吃無酵餅，就是困苦餅－你本是急忙出了埃及地－要叫你一生一世記念你從埃及地出來的日子。

Thou shalt eat no leavened bread with it; seven days shalt thou eat unleavened bread therewith, even the bread of affliction; for thou camest forth out of the land of Egypt in haste: that thou mayest remember the day when thou camest forth out of the land of Egypt all the days of thy life.
