No, your basis is not Hebrew. You've not appealed to any Hebrew source or any authority on the Hebrew language. You've simply assumed that the Bible can't be wrong.
So your argument is circular.
On the other hand your idea that "chewing the cud" is a "modern" idea is on the face of it silly. The phrase was hardly new when the KJV was translated.
So it would seem that if you have a point then there is a lot more to be said.
