ARPHAXAD
The country inhabited by Arphaxad was north of Assyria toward Armenia and the Caspian Sea. Arphaxad was the father of the Chaldeans, who before the days of Abraham migrated in such numbers to the country about Babel that the land of Shinar became equally the land of the Chaldees or Chaldeans, for the Bible says that Haran died “in the land of his nativity in Ur of the Chaldees,” and that Terah took Abram and Sarai and Lot and “went forth with them out of Ur of the Chaldees;” while as late as the time of Zechariah it is also called “the land of Shinar.” Zechariah 5:11. Under Nabopolassar, the father of Nebuchadnezzar, the Chaldeans rose to power and dominion, and under Nebuchadnezzar himself they spread their empire over all nations, as the Assyrians had done before them.
