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 Slaughter an animal from your flock or herd as the Passover sacrifice to the LORD your God. Do this at the place where the LORD will choose for his name to live.

3 Never eat leavened bread with the meat from this sacrifice. Instead, for seven days you must eat unleavened bread at this festival. (It is the bread of misery because you left Egypt in a hurry.) Eat this bread so that, as long as you live, you will remember the day you left Egypt.

4 There should be no yeast anywhere in your land for seven days. Never leave until morning any of the meat you slaughter on the evening of the first day.

5 You're not allowed to slaughter the animals for Passover in any of the cities the LORD your God is giving you.

6 Instead, slaughter your animals for Passover in the place where the LORD your God will choose for his name to live. Do this in the evening as the sun goes down. This is the same time you did it when you left Egypt.
