Gomorrah is listed in the trading records of Ebla.
Such records don’t verify any particular religious claim, just that cities with such names existed and had commerce.
The name si-da-muKI was identified as Sodom, and é-ma-raKI as Gomorrah. These identifications too have now evaporated. Let's look at Gomorrah first. The initial sign é could correctly reflect the initial ‘ayin with which Gomorrah begins in Hebrew. But the name is almost certainly not Gomorrah; much more probably it is a major town on the Euphrates River, ancient Emar, where a French team has found an archive of cuneiform tablets from the Late Bronze Age (13th century B.C.). Emar is mentioned many times in the Ebla tablets, as would be expected, for it lies at the point where travelers from Babylonia would leave the Euphrates' route to move westward to Ebla and the Mediterranean coast. Sidamu has not yet been located, but nothing favors a location near the Dead Sea (where Sodom lay), Indeed, a site in northwest Syria is indicated by the names associated with it. The only link with the biblical name is the resemblance in the sound. Similar arguments have disposed of the identification of virtually all the biblical cities supposedly mentioned in the Ebla tablets. As for the personal names mentioned in the Ebla tablets, it was never claimed that these were the same as the biblical personages. The only claim was that the names were the same. In the Fertile Crescent, where the majority of ancient peoples spoke one Semitic language or another, the same names may occur in places hundreds of miles away from each other and centuries apart. Finding Israel, Ishmael, Michael and Abram among the Ebla names was not an enormous surprise. Ishmael, for example, was a widely favored name, for it means "God has heard," probably referring to the parents' prayer for a child (compare Genesis 16:11). These names, familiar to us from the Bible, should not lead anyone to suppose there is any direct relation between the people who bore them at Ebla and the biblical characters of the same name.
