Deuteronomy 16:3–4

You shall eat no leavened bread with it. Seven days you shall eat it with unleavened bread, the bread of affliction—for you came out of the land of Egypt in haste—that all the days of your life you may remember the day when you came out of the land of Egypt. No leaven shall be seen with you in all your territory for seven days, nor shall any of the flesh that you sacrifice on the evening of the first day remain all night until morning.

Do not eat it with bread made with yeast, but for seven days eat unleavened bread, the bread of affliction, because you left Egypt in haste—so that all the days of your life you may remember the time of your departure from Egypt. Let no yeast be found in your possession in all your land for seven days. Do not let any of the meat you sacrifice on the evening of the first day remain until morning.

Do not eat leavened bread with it. For seven days you are to eat unleavened bread with it, the bread of hardship—because you left the land of Egypt in a hurry—so that you may remember for the rest of your life the day you left the land of Egypt. No yeast is to be found anywhere in your territory for seven days, and none of the meat you sacrifice in the evening of the first day is to remain until morning.

Eat it with bread made without yeast. For seven days the bread you eat must be made without yeast, as when you escaped from Egypt in such a hurry. Eat this bread—the bread of suffering—so that as long as you live you will remember the day you departed from Egypt. Let no yeast be found in any house throughout your land for those seven days. And when you sacrifice the Passover lamb on the evening of the first day, do not let any of the meat remain until the next morning.

You shall not eat with it anything leavened; seven days you shall eat with it unleavened bread of affliction, because in haste you went out from the land of Egypt, so that you will remember the day of your going out from the land of Egypt all the days of your life. And leaven shall not be seen with you in any of your territory for seven days, and none of the meat that you will slaughter on the evening on the first day shall remain overnight until morning.

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. And there shall be no leavened bread seen with thee in all thy coast seven days; neither shall there any thing of the flesh, which thou sacrificedst the first day at even, remain all night until the morning.
