Who Was Shem's Father? Genesis 11:10–26
Shem's father is Noah, a fact Genesis establishes earlier and simply assumes here. This passage answers a different question, following Shem's line from Arpachshad down to Abram.
Shem's Wife: What Genesis 11 Does Not Name
Genesis 11:10–11 tells us Shem was one hundred when Arpachshad was born, two years after the flood, and that he later had more sons and daughters. It never names his wife, and no other passage does either.
Who Was Shem to Abraham? Genesis 11:10–26
Shem was not Abraham's father but his forefather several generations back. Genesis 11:10–26 traces a named family line from Shem to Terah, and Terah fathered Abram.
Who Was Shem's Wife? Genesis 11:10–26
The Bible never names Shem's wife, and Genesis 11:10–26 gives no detail about her. What the passage does is trace the line from Shem through Arpachshad, Shelah, Eber, Peleg, Reu, Serug, Nahor and Terah to Abram.
