What Does Genesis 11:10 Mean?

This is the account of Shem's family line. Two years after the Flood, when Shem was 100 years old, he became the father of Arphaxad. The genealogy of Shem in chapter 11 provides more detail than the brief reference in chapter 10, adding the ages of the fathers at the time of birth and their total lifespans. This genealogy is the bridge from the Table of Nations to the call of Abram, narrowing the covenant line from seventy nations down to one man and his family.

The "two years after the Flood" specification is the genealogy's one chronological anchor point connecting it to the previous narrative. It grounds the genealogy in historical time relative to the great Flood, establishing that this is not an indefinite mythological genealogy but a specific sequence of historical figures with calculable dates. The genealogy, if taken at face value, allows the careful reader to work out a chronology from Shem to the call of Abram within a limited number of centuries.

Shem's genealogy is the backbone of the covenant line. Every subsequent patriarch in Genesis traces through this line. The consistent narrative purpose of the Shemite genealogy, from Genesis 5's pre-Flood version through this post-Flood continuation, is to keep the reader oriented: God's redemptive purposes are moving through history along a specific human line, and that line runs from Shem through Arphaxad and Shelah and Eber to Peleg and Reu and Serug and Nahor and Terah and finally to Abram, which is where Genesis will spend most of its remaining chapters.
