Deuteronomy 16:3-4

3Thou shalt eatH398 no leavenedH2557 breadH3899 with it; sevenH7651 daysH3117 shalt thou eatH398 unleavenedH4682 breadH3899 therewith, even the breadH3899 of affliction; for thou camest forthH3318 out of the landH776 of EgyptH4714 in hasteH2649: that thou mayest rememberH2142 the dayH3117 when thou camest forthH3318 out of the landH776 of EgyptH4714 all the daysH3117 of thy life.

4And there shall be no leavenH7603 seenH7200 with thee in all thy bordersH1366 sevenH7651 daysH3117; neither shall any of the fleshH1320, which thou sacrificest the firstH7223 dayH3117 at even, remainH3885 all night until the morningH1242.
