Do you read Hebrew in the sense that you understand its syntax and grammar? The word order is different than English, so you cannot simply take an interlinear version and get the full understanding. It's a quick path to misunderstanding if you don't check your conclusions against those of people who do understand the language (that would include all the translators).
Verse 4 clearly indicates that God expected Noah to eat animals. "Clean" and "unclean" aren't discussed in this passage, so any argument on that subject is simply without authority.
I hear what you are saying Dino, but the inter linear does take into consideration the word order. The difference of word order is the sentence starts from right and moves left whereas in English it starts left and moves right, but the sequential order is the same as in first word, second, and so on. As for syntax and grammar this is something continuously study out to give my best attempt at understanding and also research with those whom do understand to get the meaning down as close as possible but I am not perfect nor would I ever claim to be. When I read this passage from the Hebrew it reads to me (paraphrasing into English summation) as Yahweh (God) was saying that when you leave the ark not to eat animals and allow them to be fruitful and multiply, to have dominion over them and subdue them if need be, remember that when the time comes for meat to be back on the menu to not eat meat with its life force still in it and keep Kosher as in no blood in the life you consume. Please understand this is my understanding of this passage and how I take it after I have studied out the Hebrew writing and layout....
Now with that being said I will take the thought of “Noah can eat animals immediately and whatever animal he desires” and expound.... Noah eats the animals, he feeds his wife, three grown male children, and thier wives, with there being such a limited amount of each creature how long before a species becomes extinct from simply being eaten by humans? Granted one cow can feed 8 humans a bit, but with no refrigeration, and the salt supply being washed away by the flood (it would need to be replenished also) there was no way to preserve the meat once slaughtered and cooked. So therefore they would have to slaughter a decent quantity of creatures to sustain thier lives not giving enough time for reproduction of said creatures given the gestation period for most of them would be over 200 days to bring forth new young, then maturity period to get to an age worthy of becoming meat for lack of a better term. The creature that would be the quickest turn on birthing new young would be chickens which gestation period is approx 21 days from egg laid to hatched then approx 12-16 weeks for them to be mature enough to eat, cows gestation period is approx 260 days then approx a year from birth to be mature enough to eat, deer are similar with a gestation period of 220 days then at least a year or more for maturity to eat, so on and so forth. And just to go further an unclean animal (which there much less of) like a pig, there gestation period is approx 120 days and approx another year after to eat (6 months approx if it’s a factory style farm in which they didn’t have in those days). Thinking out of the box suppose they wanted to eat a lion (unclean meat) thier gestation period is 108 days and then time needed to grow to meat level. So in retrospect, the meat would run out prior to being replenished if Noah and his family were to eat them.
This is why I hold firm in the belief that there was a time where no creature ate another (humans eating animals nor animals eating other animals) like in the garden so the animals and Noah and his family would have time to be fruitful and multiply and fill the Earth once more. Now after there being a significant enough time for species to be firm and secure again I would think that meat eating would begin again as well as sacrifices. And they would know what was clean to eat and what was not because Yahweh (God) had declared what was and what wasn’t from before the flood, furthermore they knew how to sacrifice appropriately because someone had to teach the generations otherwise Abrham would t have known how to. So, in conclusion Torah was a real thing before flood, and after, and was passed as a verbal inheritance from generation to generation, and given in written form from the Almighty Himself on mt. Sinai as a contract to be part of God’s set apart people (there were other nationalities with the Israelites in the exodus and were “grafted/adopted/accepted” as native born by accepting the contract) just as we are called today to be set apart. Therein is why I follow Torah, two fold, because God said to “throughout your generations to be a sign on your forehead and hearts” and also to be set apart from the world as Yahshua (Jesus) calls us to be set apart from the world. It all clicks and makes sense and flows and is unchanging just as Yahweh Himself is the same today as yesterday and tomorrow. But I state again, this is my belief and understanding of the scriptures in its entirety and I urge whomever reads this to not take my word for it but to study and pray and seek truth.
