Son of Shem, born the year after the Deluge. He died at the age of 438 years (Gen. 11:10-13; 1 Chr. 1:17, 18; Luke 3:36). He dwelt in Mesopotamia, and became, according to the Jewish historian Josephus, the progenitor of the Chaldeans. The tendency is to recognize in the word the name of the country nearest the ancient domain of the Chaldeans. Some regard the word as an Egypticized form of the territorial name of Ur Kasdim, or Ur of the Chaldees.
Arphaxad
Arphaxad is a name that turns up in a family line, three times over. He is a son of Shem, born “two years after the flood” (Genesis 11:10), and he fathers Shelah, who in turn fathers Eber. Chronicles repeats the line, and Luke carries it forward when he lists the ancestors of Jesus (Luke 3:36). Nothing is told about Arphaxad himself beyond his years and his children. Still, the repeated record shows how carefully Scripture keeps track of who came from whom, so that the story reaches from Noah’s sons to later generations. Read Genesis 11:10-17 to see the chain unfold.
