Enochian defined by John Dee and Edward Kelly, who lived in the late 1600’s is an occult language claimed to be angelic. There was a prophet, named Enoch in the Old Testament that was a righteous man and the city that he lived in was very righteous as well, that the Lord brought him and the people that lived in that city to dwell with him in Heaven. If I have hypothesized correctly, the reason this language was given the name Enochian because just as Enoch and his people were lifted up because of their righteousness before God so is the language named because of the claim of it to be angelic. This meaning that it the word Enochian could have been derived from the name of the righteous Prophet Enoch.
