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 Therefore you shall sacrifice the Passover to the Lord your God, from the flock and the herd, in the place where the Lord chooses to put His name.

3 You shall eat no leavened bread with it; seven days you shall eat unleavened bread with it, that is, the bread of affliction (for you came out of the land of Egypt in haste), that you may remember the day in which you came out of the land of Egypt all the days of your life.

4 And no leaven shall be seen among you in all your territory for seven days, nor shall any of the meat which you sacrifice the first day at twilight remain overnight until morning.

5 You may not sacrifice the Passover within any of your gates which the Lord your God gives you;

6 but at the place where the Lord your God chooses to make His name abide, there you shall sacrifice the Passover at twilight, at the going down of the sun, at the time you came out of Egypt.
