How Did Noah Know Which Animals Were Clean & Which Were Unclean?

This is one of those situations where you have to look outside of what is specifically stated in the Bible and apply some discertion to what you're reading. It's hard work! I actually hadn't considered this until I found it here. Very good question! I knew the difference between a clean and an unclean animal but how Noah was to know stumped me since the definitions of clean and unclean don't appear in the Bible until Leviticus (which I had to look up). I found an interesting link that you might find useful. To me it makes perfect sense. That being said, it's probably important to point out that I am in no way a Biblical literalist. I find that the Bible is the gateway to understanding God and my relationship with Him. I do not think that the Bible is the "law". That being said, I hope you enjoy the link and that it is helpful to you. God Bless! Here's the link. I hope it works, I had to type it in, my rating is not high enough to paste links yet. http://gracethrufaith.com/ask-a-bible-teacher/animals-on-the-ark/

God told him. Since the instruction comes from God, so it is understandable that Noah was also instructed which animals are unclean and which animals are clean. And it's 7 pairs of clean animals, and 2 pairs of unclean animals (Genesis 7:2)

God just sent the animals to the ark and Noah let them in. He didn't worry about who is clean and not clean animals. God told him which animals would enter the ark. The bible don't really explain much about this issue.

From Creation, believers have known which animals are kosher or clean and which are not. Clean animals are those with cloven hooves and chew their cud...Clean birds are those whose nostrils go into the face and not through the beak..(buzzards,eagles, eat carrion and have nostrils that go through and through so that they can blow the carrion that gets stuck there out.Birds cannot breathe well through their mouths.) Clean fish are those with fins and scales...

I am sure Noah is not a dufus who can't differentiate between a clean and an unclean animal. He must have a pair of eye on him that enable him to see instead of guessing or assuming through touching. Many children have no problem telling you which animal is clean or which is unclean, it is not something that one need to be in possess a rocket science degree or PHD in medicine in order to know.

I am christian, and as they said, Noah did not know. God gave him the power to understand. Also unclean animals were the ones who ate meat, and blood. Merry Christmas.

The Bible is not a detailed history of every event. It tells us what we need to know. Be good and you will live when Noah is brought back to life and you can ask him all the questions you want.

God probably told him which animals were clean and unclean. He might have known about some of them too.

I am pretty sure God told him which ones were which.

I am not sure with my answer, this is only based on what I heard from our church. Unclean animals are those animals which can kill humans and eat flesh and meat. And clean animals are those who only eats plants.
