Deuteronomy 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).

Deuteronomy 16:4 In-Context

2 Thou shalt, therefore, sacrifice the passover unto the LORD thy God, of the sheep and the cows, in the place which the LORD shall choose to cause his name to dwell therein.

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.

5 Thou may not sacrifice the passover within any of thy gates (or within any of thy towns) which the LORD thy God gives thee

6 but at the place which the LORD thy God shall choose to cause his name to dwell in; there thou shalt sacrifice the passover in the evening, at the going down of the sun, at the appointed time when thou came forth out of Egypt.
