申命记 16:3

你吃这祭牲，不可吃有酵的饼；七日之内要吃无酵饼，就是困苦饼—你本是急忙出了埃及地—要叫你一生一世记念你从埃及地出来的日子。

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.
