It's important to remember that:
* The Bible is a religious text, not a historical record. While it contains stories and accounts, these are often interpreted through a religious lens.
* The location of Sodom is debated. Some scholars believe it was in the Dead Sea region, while others place it elsewhere in the Levant.
* Languages in the ancient world were fluid and diverse. It's likely that multiple languages were spoken in the area, even within the same city.
Therefore, we can't definitively say what language was spoken at Sodom based on the Bible.
