Devarim 16:4 Meaning and Commentary

Deuteronomy 16:4

And there shall be no leavened bread seen with thee in all thy
coasts seven days
For before the passover they were to search diligently every room in the house, and every hole and crevice, that none might remain any where; see ( Exodus 12:15 Exodus 12:19 ) ( 13:7 ) ,

neither shall there be anything of the flesh, which thou sacrificedst
the first day at even, remain all night until the morning;
which may be understood both of the flesh of the passover lamb, as Aben Ezra, according to ( Exodus 12:10 ) and of the flesh of flocks and herds, or of the Chagigah; according to Jarchi this Scripture speaks of the Chagigah of the fourteenth, which was not to remain on the first day of the feast (the fifteenth) until the morning of the second day (the sixteenth).

Devarim 16:4 In-Context

2 Thou shalt therefore sacrifice the Pesach unto Hashem Eloheicha, of the tzon and the herd, in the place which Hashem shall choose to place Shmo there.

3 Thou shalt eat no chametz with it; shivat yamim shalt thou eat matzot therewith, even the lechem oni (bread of affliction); for thou camest forth out of Eretz Mitzrayim in haste in order that thou mayest remember the yom when thou camest forth out of Eretz Mitzrayim kol yemei chayyechah (all the days of thy life).

4 And there shall be no se’or (leaven) seen with thee in all thy territory shivat yamim; neither shall there any thing of the basar, which thou sacrificedst ba’Erev baYom HaRishon, remain overnight until the boker.

5 Thou mayest not sacrifice the Pesach within any of thy she’arim, which Hashem Eloheicha giveth thee;

6 But at the place which Hashem Eloheicha shall choose to place Shmo in, there thou shalt sacrifice the Pesach at erev, at the going down of the shemesh, at the mo’ed (appointed time) that thou camest forth out of Mitzrayim.
