Was Arphaxad the first Ubaid ?

Here are two questions ,Was Arphaxad the first Ubaid and did the word Sumer from from the Shem in the Bible?We will discuss the matter today.So who was Arphaxad ,his name was Arpakhshad אַרְפַּכְשַׁד and he was a son of Shem from the book of Genesis.He had a son ,Shelah which means sent and maybe a son named Keinan in other non Biblical texts and in the Bible he was the grandfather of Eber where the name Hebrew comes from.

But was he the forefather of the Ubaid people ,an ancient Mesopotamian people who pre dated the Sumerians.The Bible does not say much about him but here is what the Book of Jubilees has to say on him in chapter 8.1

“In the twenty-ninth jubilee, in the first week, in the beginning thereof Arpachshad took to himself a wife and her name was Râsû’ĕjâ, [the daughter of Sûsân,] the daughter of Elam,

ותלד לו בן בשנה השלישית לשבוע הזה ויקרא את שמו קינם:

and she bare him a son in the third year in this week, and he called his name Kâinâm.

ויגדל בנו וילמדהו אביו ספר, וילך לבקש לו מקום לבנות לו שם עיר מושב:

And the son grew, and his father taught him writing, and he went to seek for himself a place where he might seize for himself a city.”

My first thought being this may have been where Sumerian Cuneiform came from if Keinan and Arpakhshad invented writing here but I don’t see a Ubaid connection yet.It has always been my thoughts that the Ubaid’s were antediluvian or pre flood and were Adamic people and that Sumer was the first post diluvian culture.Interestingly there was an ancient city in northern Iraq called Arpachiyah near ancient Nineveh however this is a Assyrian or at that time Akkdadian part of Iraq not the cities Ur and Eridu that Ubaid is associated with.Although some Ubaid pottery has been found in the Syrian region further north.Have I been wrong in thinking Ubaid was pre flood ,maybe , but I don’t see a connection with the Ubaid’s and Sumer which was worlds first real nation and we know Nimrod and Kush from the Babel story ruled a great nation and Arpakhshad would have lived in a similar time as Kush both being grandsons of Noah.

This is from creation.com

“Josephus¹³ identifies the descendants of Arphaxad as the Chaldeans and this seems to be consistent with the biblical statements concerning them, for Abraham was a descendant of Arphaxad (Genesis 10:24 and 11:10–31). Abraham left Ur of the Chaldees to eventually travel to the land of Canaan.”

That seems like the main evidence connecting Arpakhshad with Sumer but also Jubilees equates Arpakhshad with the creation of writing and Sumer had the first writing.

This also from creation.com sort of connecting Sumer with Assyrian Nineveh in the north.

Asshur and Samarra – The Early Assyrians

“The Bible identifies Nimrod as travelling to the land of ASSHUR (Assyria), and building Nineveh. Without doubt the semitic Assyrians had been a long time in that region of the world when the later Assyrian empire flourished. If the first city of Nineveh was built by Nimrod (from Sumer), into what culture archaeologically did he travel? Without doubt the early geographically related culture at the time of Nineveh’ first and second cities was SAMARRA.”

So maybe I was wrong and Ubaid was Sumer however or maybe not we just do not know. I don’t see anything proven it could still be true that Ubaid culture was Sumer antediluvian and then in and around Babel Nimrod (Etana of Kish) set up the empire of Sumer (or Kengir) or it is possible that the Ubaids were the Kengir.

So the next question is was Sumer named for Shem? First lets start with what does Shem mean,it literally means name but also can mean reputation or honor.Like the great 18th century Ukrainian Rabbi Baal Shem Tov ,which literally means master of the good name but actually truly means “The one with the good reputation”

Sumer was the Akkadian name for Kengir (the real name of Sumer) but both names mean “land of the nobles”.The meaning could be similar in some ways that Shem would have been a name of great honor.And there is a phonetic similarity between Sumer and Sem if you drop the Hebrew letter hei in Shem.So yes there could be a Shem/Sumer connection and I have always believed Emegir the language of the kengir (Sumer) was the first semitic language.I do not doubt at all that the Sumerian Cuneiform inspired the Akkadian style which led to the eastern Semitic Aramaic.

So I think in both questions posed that the answer is very possible but I do not know for sure.

Thank you all and God Bless!
