Then what is the point of these verses in Genesis 9?
Chapter 9 follows a typical dietary prohibition syntax:
Genesis 9:3 states:
Every moving thing that lives shall be food for you; and just as I gave you the green plants, I give you everything.
Genesis 9:3
Some people read this verse in scripture and think that this is the first time God sets a rule in which people can eat meat. However, if we read the verse right before and after it:
A. The fear and dread of you shall rest on every animal of the earth, and on every bird of the air, on everything that creeps on the ground, and on all the fish of the sea; into your hand they are delivered.
Every moving thing that lives shall be food for you; and just as I gave you the green plants, I give you everything.
B.
Only, you shall not eat flesh with its life, that is, its blood.
Genesis 9:2-4
And what we see is that God says that the fear of dread is on every animal, into your hand they're delivered, and Every moving thing that lives shall be food for you. then afterwards it says "only you shall not eat flesh with it's life, that is, it's blood".
So now that we've read the full passage, now we can examine what it means.
Compare:
A.
Any animal that divides the hoof and has the hoof cleft in two, and chews the cud, among the animals, you may eat.
B.
Yet of those that chew the cud or have the hoof cleft you shall not eat these: the camel, the hare, and the rock badger, because they chew the cud but do not divide the hoof; they are unclean for you.
Deuteronomy 14:6-7
A
Of all that live in water you may eat these: whatever has fins and scales you may eat.
B.
And whatever does not have fins and scales you shall not eat; it is unclean for you.
Deuteronomy 14:9-10
A.
You may eat any clean birds.
B.
But these are the ones that you shall not eat: the eagle, the vulture, the osprey,
Deuteronomy 14:11-12
A.
These you shall eat, of all that are in the waters. Everything in the waters that has fins and scales, whether in the seas or in the streams—such you shall eat.
B.
But anything in the seas or the streams that does not have fins and scales, of the swarming creatures in the waters and among all the other living creatures that are in the waters—they are detestable to you.
Leviticus 11:9-10
Notice the order in which the ancient Hebrews wrote out their dietary laws. A. Are things already approved and being consumed, B. Is a sub-specification that clarifies the ruling.
Any animals that divides the hoof, yet of those that chew the cud.
Of all that lives in water, and whatever does not have fins and scales.
All that are in the waters but not those without fins or scales.
You may eat any clean birds, but...these are the ones you shall not eat.
In every instance we see the dietary law starts out by describing what was already allowed and approved for eating, and then it follows with the updated ruling.
So now let's go back to the dietary ruling in Genesis and re-read it.
A. The fear and dread of you shall rest on every animal of the earth, and on every bird of the air, on everything that creeps on the ground, and on all the fish of the sea; into your hand they are delivered.
Every moving thing that lives shall be food for you; and just as I gave you the green plants, I give you everything.
B.
Only, you shall not eat flesh with its life, that is, its blood.
Genesis 9:2-4
We see the ruling in Genesis 9:4 (no animals with lifeblood), following that which was already allowed (The fear and dread of you shall rest on every animal of the earth, and on every bird of the air, on everything that creeps on the ground, and on all the fish of the sea; into your hand they are delivered).
And so when we read the dietary law in context, we see that people didn't just randomly switch from vegans to eating meat. Rather, people always ate meat, going back to when God called on man to subdue fish and birds. When Abel gave God the fat portions in Gen 4:4, he likely ate the fresh meat. Rather than just leaving it out to rot. Just as people were already eating cows and fish and birds in Deuteronomy and Leviticus. God wasn't saying "you've never eaten fish before but now it's ok to eat them", God states that which was already approved first, which people in the times of Deuteronomy and Leviticus were already eating, and that people were already approved to eat fish, and then God clarifies on a new subset dietary ruling, that fish without scales is more specifically now what is not approved.
And the above versus are not exhaustive, there are at least a dozen dietary rulings that are all structured with the same Hebrew syntax in the Old testament.
And all this ties into the reality that there was always death, and it was acceptable to God, going back to the earliest days of creation.
