Serug .

• Genesis 11:20-23
• Jubilees 11:1-2 States that his original name was Seroh, but that it was changed to Serug in the time when Noah's children began to fight wars, and the city of Ur was built, where Serug lived. It says this Serug was the first of the patriarchal line to abandon monotheism and turn to idol worship, teaching sorcery to his son Nahor.

Book of Jubilees that refer to Serug/Sêrôḫ:

And in the thirty-fifth jubilee, in the third week, in the first year thereof, Reu took to himself a wife, and her name was ’Ôrâ, the daughter of ’Ûr, the son of Kêsêd, and she bare him a son, and he called his name Sêrôḫ,

6. For this reason he called the name of Sêrôḫ, Serug, for every one turned to do all manner of sin and transgression. 7. And he grew up, and dwelt in Ur of the Chaldees, near to the father of his wife's mother, and he worshipped idols, and he took to himself a wife in the thirty-sixth jubilee, in the fifth week, in the first year thereof, and her name was Mêlkâ, 2 the daughter of Kâbêr, the daughter of his father's brother. 8. And she bare him Nahor, in the first year of this week, and he grew and dwelt in Ur of the Chaldees, and his father taught him the researches of the Chaldees to divine and augur, according to the signs of heaven.

The legend about Sargon has undoubtedly a historical kernel. He is said to have come down on the Euphrates, floating in a reed chest, and having been saved by a water carrier of Agade, to have been reared there and become finally king of that place. May not this indicate a Semitic migration from the north, along the Euphrates, down to Agade?

Now the Bible mentions a certain Serug,' a descendant of Shem. If I am right, the names of these patriarchs may stand for ancient Semitic dynasties. Several scholars think that Serug represents Sargon Agade, and in my opinion, it stands for the Sargon Dynasty of Agade. We know that both Sargon and his son Naram-Sin were regarded as gods, and the "god" determinative was appended to their names. Sargon, Bab. Shargani, may have arisen from Serug-an, "an" being the god-determinative which the biblical author omitted. There was an ancient locality in Northern Mesopotamia between the Euphrates and the Balikh rivers, that was called Sarug, and it is possible that the Sargon Dynasty and the Semites of Agade come from this place. Sargon conquered, not only Agade, but a large part of Babylonia, Mariu, the kingdom of Gutiumin Kurdistan and also made war expeditions into Elem. While Sargon (I) only mentions as his title the first one that he acquired when he became king of Agade, namely Sharali, "city king," his son Naram-Sin assumed the proud title "king of the Four Regions." What this title precisely means is still a debated question. Several scholars have assumed that it denotes the four world regions, including Syria in the west and the highlands of Media to the east. I am not prepared to accept this explanation.
