Deuteronomy 16:3-4 Thou shalt eat no leavened bread with it; seven days shalt thou eat unleavened bread therewith, even the bread of affliction; for in haste didst thou come forth out of the land of Egypt; that thou mayest remember the day when thou camest forth out of the land of Egypt all the days of thy life.

JPS_ASV_Byz⁽ⁱ⁾ ³ Thou shalt eat no leavened bread with it; seven days shalt thou eat unleavened bread therewith, even the bread of affliction; for in haste didst thou come forth out of the land of Egypt; that thou mayest remember the day when thou camest forth out of the land of Egypt all the days of thy life. ⁴ And there shall be no leaven seen with thee in all they borders seven days; neither shall any of the flesh, which thou sacrificest the first day at even, remain all night until the morning.
