Historians as well as Bible scholars consider the biblical account about Chedorlaomer's campaign against Sodom as a pious fiction but a chronological reconstruction based on synchronisms shows that among dynasties from Sumerian lists the 3rd and last Elamite king of the Awan I dynasty was indeed Kudur-Lagamar (1990-1954). The route of Chedorlaomer shows that this king came to this region near Egypt in order to maintain control over this new land trade route. This ambitious project had to have worried Amenemhat I (1975-1946) and to block the progress of this powerful Mesopotamian king, he built the Walls of the Ruler and planned to create an Amorite rival confederation. In order to achieve his goal he proposed an alliance to Abram, who came from Shinar (Sumer), a region close to Elam, and began preparations by appointing Sarai as a bearer of offering to his personal service, then by marrying her to seal this alliance (Gn 12:19). The wedding was cancelled, but the statue remained.
