This chapter evidently incorporates a contemporary account of the events recorded. So antique a document was it even when it found its place in this book, that the editor had to modernize some of its expressions that it might be intelligible. The places mentioned were no longer known by the names here preserved--Bela, the vale of Siddim, En-mishpat, the valley of Shaveh, all these names were unknown even to the persons who dwelt in the places once so designated. It can scarcely have been Abram who wrote down the narrative, for he himself is spoken of as Abram the Hebrew, the man born beyond the Euphrates, which is a way of speaking of himself no one would naturally adopt. From the clear outline given of the route followed by the expedition of Chedorlaomer, it might be supposed that some old staff-secretary had reported on the campaign. However that may be, the discoveries of the last two or three years have shed light on the outlandish names that have stood for four thousand years in this document, and on the relations subsisting between Elam and Palestine. On the bricks now preserved in our own British Museum the very names we read in this chapter can be traced, in the slightly altered form which is always given to a name when pronounced by different races. Chedorlaomer is the Hebrew transliteration of Kudur Lagamar; Lagamar was the name of one of the Chaldean deities, and the whole name means Lagamar's son, evidently a name of dignity adopted by the king of Elam. Elam comprehended the broad and rich plains to the east of the lower course of the Tigris, together with the mountain range (8,000 to 10,000 feet high) that bounds them. Elam was always able to maintain its own against Assyria and Babylonia, and at this time it evidently exercised some kind of supremacy not only over these neighbouring powers, but as far west as the valley of the Jordan. The importance of keeping open the valley of the Jordan is obvious to every one who has interest enough in the subject to look at a map. That valley was the main route for trading caravans and for military expeditions between the Euphrates and Egypt. Whoever held that valley might prove a most formidable annoyance and indeed an absolute interruption to commercial or political relations between Egypt and Elam, or the Eastern powers. Sometimes it might serve the purpose of East and West to have a neutral power between them, as became afterwards clear in the history of Israel, but oftener it was the ambition of either Egypt or of the East to hold Canaan in subjection. A rebellion therefore of these chiefs occupying the vale of Siddim was sufficiently important to bring the king of Elam from his distant capital, attaching to his army as he came, his tributaries Amraphel king of Shinar or northern Chaldea, Arioch king of a district on the east of the Euphrates, and finally Tidal, or rather Tur-gal _i.e._ the great chief, who ruled over the nations or tribes to the north of Babylonia.
