It was probably during one of the intervals of this stormy period that the rival kings in Babylonia joined forces against a common enemy and invaded the Western Land. Probably there was much unrest there. Great ethnic disturbances were in progress which were changing the political complexion of Western Asia. In addition to the outpourings of Arabian peoples into Palestine and Syria, which propelled other tribes to invade Mesopotamia, northern Babylonia, and Assyria, there was also much unrest all over the wide area to north and west of Elam. Indeed, the Elamite migration into southern Babylonia may not have been unconnected with the southward drift of roving bands from Media and the Iranian plateau.

It is believed that these migrations were primarily due to changing climatic conditions, a prolonged "Dry Cycle" having caused a shortage of herbage, with the result that pastoral peoples were compelled to go farther and farther afield in quest of "fresh woods and pastures new". Innumerable currents and cross currents were set in motion once these race movements swept towards settled districts either to flood them with human waves, or surround them like islands in the midst of tempest-lashed seas, fretting the frontiers with restless fury, and ever groping for an inlet through which to flow with irresistible force.

The Elamite occupation of Southern Babylonia appears to have propelled migrations of not inconsiderable numbers of its inhabitants. No doubt the various sections moved towards districts which were suitable for their habits of life. Agriculturists, for instance, must have shown preference for those areas which were capable of agricultural development, while pastoral folks sought grassy steppes and valleys, and seafarers the shores of alien seas.

Northern Babylonia and Assyria probably attracted the tillers of the soil. But the movements of seafarers must have followed a different route. It is possible that about this time the Phoenicians began to migrate towards the "Upper Sea". According to their own traditions their racial cradle was on the northern shore of the Persian Gulf. So far as we know, they first made their appearance on the Mediterranean coast about 2000 B.C., where they subsequently entered into competition as sea traders with the mariners of ancient Crete. Apparently the pastoral nomads pressed northward through Mesopotamia and towards Canaan. As much is suggested by the Biblical narrative which deals with the wanderings of Terah, Abraham, and Lot. Taking with them their "flocks and herds and tents", and accompanied by wives, and families, and servants, they migrated, it is stated, from the Sumerian city of Ur northwards to Haran "and dwelt there". After Terah's death the tribe wandered through Canaan and kept moving southward, unable, it would seem, to settle permanently in any particular district. At length "there was a famine in the land"--an interesting reference to the "Dry Cycle"--and the wanderers found it necessary to take refuge for a time in Egypt. There they appear to have prospered. Indeed, so greatly did their flocks and herds increase that when they returned to Canaan they found that "the land was not able to bear them", although the conditions had improved somewhat during the interval. "There was", as a result, "strife between the herdmen of Abram's cattle and the herdmen of Lot's cattle."

It is evident that the area which these pastoral flocks were allowed to occupy must have been strictly circumscribed, for more than once it is stated significantly that "the Canaanite and the Perizzite dwelled in the land". The two kinsmen found it necessary, therefore, to part company. Lot elected to go towards Sodom in the plain of Jordan, and Abraham then moved towards the plain of Mamre, the Amorite, in the Hebron district.[[272]] With Mamre, and his brothers, Eshcol and Aner, the Hebrew patriarch formed a confederacy for mutual protection.[[273]]

Other tribes which were in Palestine at this period included the Horites, the Rephaims, the Zuzims, the Zamzummims, and the Emims. These were probably representatives of the older stocks. Like the Amorites, the Hittites or "children of Heth" were evidently "late comers", and conquerors. When Abraham purchased the burial cave at Hebron, the landowner with whom he had to deal was one Ephron, son of Zohar, the Hittite.[[274]] This illuminating statement agrees with what we know regarding Hittite expansion about 2000 B.C. The "Hatti" or "Khatti" had constituted military aristocracies throughout Syria and extended their influence by forming alliances. Many of their settlers were owners of estates, and traders who intermarried with the indigenous peoples and the Arabian invaders. As has been indicated (Chapter I), the large-nosed Armenoid section of the Hittite confederacy appear to have contributed to the racial blend known vaguely as the Semitic. Probably the particular group of Amorites with whom Abraham became associated had those pronounced Armenoid traits which can still be traced in representatives of the Hebrew people. Of special interest in this connection is Ezekiel's declaration regarding the ethnics of Jerusalem: "Thy birth and thy nativity", he said, "is of the land of Canaan; thy father was an Amorite, and thy mother an Hittite."[[275]]

It was during Abraham's residence in Hebron that the Western Land was raided by a confederacy of Babylonian and Elamite battle lords. The Biblical narrative which deals with this episode is of particular interest and has long engaged the attention of European scholars:

"And it came to pass in the days of Amraphel (Hammurabi) king of Shinar (Sumer), Arioch (Eri-aku or Warad-Sin) king of Ellasar (Larsa), Chedor-laomer (Kudur-Mabug) king of Elam, and Tidal (Tudhula) king of nations; that these made war with Bera king of Sodom, and with Birsha king of Gomorrah, Shinab king of Admah, and Shemeber king of Zeboiim, and the king of Bela, which is Zoar. All these joined together in the vale of Siddim, which is the salt sea. Twelve years they served Chedor-laomer, and in the thirteenth year they rebelled."[[276]] Apparently the Elamites had conquered part of Syria after entering southern Babylonia.

Chedor-laomer and his allies routed the Rephaims, the Zuzims, the Emims, the Horites and others, and having sacked Sodom and Gomorrah, carried away Lot and "his goods". On hearing of this disaster, Abraham collected a force of three hundred and eighteen men, all of whom were no doubt accustomed to guerrilla warfare, and delivered a night attack on the tail of the victorious army which was withdrawing through the area afterwards allotted to the Hebrew tribe of Dan. The surprise was complete; Abraham "smote" the enemy and "pursued them unto Hobah, which is on the left hand of Damascus. And he brought back all the goods, and also brought again his brother Lot, and his goods, and the women also, and the people."[[277]]

The identification of Hammurabi with Amraphel is now generally accepted. At first the guttural "h", which gives the English rendering "Khammurabi", presented a serious difficulty, but in time the form "Ammurapi" which appears on a tablet became known, and the conclusion was reached that the softer "h" sound was used and not the guttural. The "l" in the Biblical Amraphel has suggested "Ammurapi-ilu", "Hammurabi, the god", but it has been argued, on the other hand, that the change may have been due to western habitual phonetic conditions, or perhaps the slight alteration of an alphabetical sign. Chedor-laomer, identified with Kudur-Mabug, may have had several local names. One of his sons, either Warad-Sin or Rim-Sin, but probably the former, had his name Semitized as Eri-Aku, and this variant appears in inscriptions. "Tidal, king of nations", has not been identified. The suggestion that he was "King of the Gutium" remains in the realm of suggestion. Two late tablets have fragmentary inscriptions which read like legends with some historical basis. One mentions Kudur-lahmal (?Chedor-laomer) and the other gives the form "Kudur-lahgumal", and calls him "King of the land of Elam". Eri-Eaku (?Eri-aku) and Tudhula (?Tidal) are also mentioned. Attacks had been delivered on Babylon, and the city and its great temple E-sagila were flooded. It is asserted that the Elamites "exercised sovereignty in Babylon" for a period. These interesting tablets have been published by Professor Pinches.
