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 thou didst come forth out of the land of Egypt in haste; that thou may remember the day when thou didst come forth out of the land of Egypt all the days of thy life.

EJ2000⁽ⁱ⁾ ³ Thou shalt eat no leavened bread with it; seven days shalt thou eat unleavened bread therewith, even the bread of affliction; for thou didst come forth out of the land of Egypt in haste; that thou may remember the day when thou didst come forth out of the land of Egypt all the days of thy life. ⁴ And there shall be no leavened bread seen in thee within all thy borders for seven days; neither shall any of the flesh which thou didst sacrifice the evening of the first day remain all night until the morning.
