"And Nimrod was a mighty hunter before the Lord; wherefore it is said, Even as Nimrod the mighty hunter before the Lord. And the beginning of his kingdom was Babel, and Erech, and Accad, and Calnch, in the land of Shinar. Out of that land went forth Asshur, and builded Nineveh, and the city Rehoboth, and Calah. And Resen between Nineveh and Calah; the same is a great city. * * * * * "And Terah took Abram his son, and Lot the son of Haran, his son's son, and Sarai his daughter-in-law, his son Abram's wife; and they went forth with them from Ur of the Chaldees, to go into the land of Canaan; and they came unto Haran, and dwelt there."--_Genesis 10 and 11._ The first great Semitic invasion took place probably about the beginning of the fourth millennium B.C., and it seems impossible to assign to it a more definite date. The later Babylonians, like the Chinese, gave great antiquity to their nation, reckoning back into hundreds of thousands of years. Their beginnings belonged to so remote a time that adding years inconceivably was but another way of saying that certain events happened very long ago, so long, indeed, that no record or monument remained to give evidence of events which had survived only in stories handed down, from father to son, for thousands of generations. Like the Hebrews and Arabs, these people belonged to the Semitic race, and from whence they came has long been a matter of conjecture. Scholars are now agreed that Arabia had been their home and that there they had lived as shepherds and herdsmen. They poured in overwhelming forces into the land of Chaldea, killing some of the inhabitants, driving others out of the country, and assimilating the rest. The Chaldeans had reached a much higher degree of culture than their conquerors, who rapidly took on the civilization of their adopted country. As in England the Saxon and Norman for some generations after the conquest pursued each his native life and customs, little influenced by the other, so in Chaldea at first the Semitic herdsman followed his pastoral life outside the brick-walled cities of the Chaldeans.
