Of course, one of the principal things confirming the identification of Ḫammurabi with Amraphel would naturally be the occurrence of one or more of the names recorded in Gen. xiv., in conjunction with his, or in such a way that a connection could be established. This, naturally, is difficult, principally on account of our having no continuous history of the period to which these rulers belong. Nevertheless, a close examination of the inscriptions suggests in what way confirmation of the events narrated with reference to Amraphel and his allies might be sought. Reference has already been made to Rîm-Sin, king of Yamutbālu (or Emutbālu), who appears to have been defeated by Ḫammurabi in the thirty-first regnal year. From this time the dominions of Rîm-Sin evidently formed part of the Babylonian Empire, and were never again separated from it as long as it existed. Notwithstanding the early identification of Rîm-Sin with Eri-Sin or Eri-Aku by the late George Smith, considerable doubt has been thrown on the identity of these two names by the fact, that in inscriptions containing the name of Kudur-mabuk, the father, the name of his son is written with _Eri_ as the first element—not _Rîm_. This, it must be admitted, is a considerable difficulty. Winckler, however, in the _Keilinschriftliche Bibliothek_, Band III., 1 Hälfte, pp. 88-89, publishes a text given by Lenormant, _Textes Inédits_, No. 70, in which the name of the son of Kudur-mabuk is written Ri-im-Sin, and if this be correctly copied, it would seem to settle the matter of their identity. It is to be noted that they are both called king of Uriwa, king of Larsa, and king of Šumer and Akkad. In the inscriptions Eri-Aku or Eri-Sin also calls himself _adda Emutbala_, “father of Yamutbālu,” and, as the colophon-date of the 31st year of Ḫammurabi shows, Rîm-Sin or Rîm-Aku was also king of that region. In these circumstances, there is hardly any doubt that they were at least closely connected, if not (as has been supposed since the time of the Assyriologist George Smith) actually identical. It is therefore worthy of mention, that M. F. Thureau-Dangin, the well-known French Assyriologist, suggests that Eri-Aku and Rîm-Sin were brothers, sons of Kudur-mabuk, and successively kings of Larsa (_Les Inscriptions de Šumer et d’Akkad_, p. 300, n. 3). This would not only account for their having the same parentage, but also for their claiming the same titles. It can therefore not be said, that Ḫammurabi became the enemy of his old ally—it was against his brother that he fought.
