Take with you seven pairs of every kind of clean animal, a male and its mate, and one pair of every kind of unclean animal, a male and its mate, and also seven pairs of every kind of bird, male and female, to keep their various kinds alive throughout the earth. Genesis 7:2, 3
This was God’s instruction to Noah.
… which suggests that Noah knew what the clean and unclean laws were. As far as I can find though, this is the first mention.
Did God change is mind?
God is not human, that he should lie, not a human being, that he should change his mind. Does he speak and then not act? Does he promise and not fulfill? Numbers 23: 19
For I, the LORD, do not change; therefore you, O sons of Jacob, are not consumed. From the days of your fathers you have turned aside from My statutes and have not kept them. Return to Me, and I will return to you,” says the LORD of hosts. “But you say, ‘How shall we return?’…Malachi 3: 6
The last verse shows why we should be grateful He changes not. But not to digress…
In the New Testament…
Every good and perfect gift is from above, coming down from the Father of the heavenly lights, who does not change like shifting shadows. Jas 1: 17 (Bolding mine)
In most instances quoted, the fact that God does not change is a promise. How could we trust someone, even God, if we were never sure how he/He would react.
Then surely the same thing counts for His instructions. At the beginning God set in place His laws, amongst which were the clean/unclean laws.
Although I knew nothing of them at the time, I had an unpleasant experience with pork. When I was in my nurse training, for the first time (we were not a well off family) I ate a roast pork lunch in the hospital dining room… and had diarrhoea later. (It happened on another occasion in a different place, so I learnt to avoid pork.)
There are some incredible tales of the ‘nasties’ that pig/swine flesh carries.
One of these…
Then there are prawns and lobsters/crayfish.
Many people have fatal, or near fatal allergies to them.
The reason God gave the clean/unclean food laws is not given.
What do pigs eat?
Pigs eat plants and animals as they are omnivores. Pigs eat almost any kind of food, including dead insects, worms, trees, bark, garbage and even dead pigs.
Eat mammals, fish, eggs, insects, molluscs, birds, reptiles and carrion. They also fight with each other over food.
Then there are buzzards and vultures and other carrion birds
Vultures clean the earth from the decaying corpse of dead animals, food waste. Their main food is carrion. Larger vultures sometimes attack smaller animals, insects, snails, eggs of birds. The Egyptian vulture eats garbage in the cities.
Obviously they all have a purpose, although it seems to me to be their primary purpose is of garbage disposal, perhaps even population control.
Not the most appetising diet 🙂
