The Ebla tablets are very interesting as to "extra-biblical" references to the Bible:
One contribution is in relation to
Genesis 14. Critics have have described the victory of Abraham over Chedorlaomer and the Mesopotamian kings as fictitious and the five Cities of the Plain (Sodom, Gomorrah, Admah, Zeboiim and Zoar) as legendary.
Genesis 14:8 And there went out the king of Sodom, and the king of Gomorrah, and the king of Admah, and the king of Zeboiim, and the king of Bela (the same is Zoar

and they joined battle with them in the vale of Siddim
The Ebla archives, however, refer to all five Cities of the Plain and on one tablet the cities are listed in the exact same sequence as
Genesis 14. The tablets further reflect that the region was prosperous and successful with a patriarchal culture consistent with that recorded in Genesis prior to the catastrophe recorded in
Genesis 14.
