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 You shall sacrifice the Passover to Yahweh your God, of the flock and the herd, in the place which Yahweh shall choose, to cause his name to dwell there.

3 You shall eat no leavened bread with it; seven days shall you eat unleavened bread therewith, even the bread of affliction; for you came forth out of the land of Egypt in haste: that you may remember the day when you came forth out of the land of Egypt all the days of your life.

4 There shall be no yeast seen with you in all your borders seven days; neither shall any of the flesh, which you sacrifice the first day at even, remain all night until the morning.

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

6 but at the place which Yahweh your God shall choose, to cause his name to dwell in, there you shall sacrifice the Passover at even, at the going down of the sun, at the season that you came forth out of Egypt.
