A prevalent misinterpretation takes the phrase 'the earth divided' literally as a cataclysmic geological event, such as continents rapidly splitting apart during Peleg's brief lifetime around 100 years post-flood, often tied to young-earth theories of accelerated plate tectonics. This overlooks the ethnographic context of Genesis 10, where 'earth' (erets) refers to the inhabited world and peoples, not landmasses, and anticipates the Babel dispersion by linguistic confusion rather than physical rifting, distorting the passage's focus on human nations originating from Noah's descendants.
Genesis 10:25
King James Version (1769)
25 And unto Eber were born two sons: the name of one was Peleg; for in his days was the earth divided; and his brother’s name was Joktan.
Genesis 10:25 records a key point in Shem's genealogy, naming Peleg, one of Eber's sons, whose lifetime coincided with the division of the earth, signifying the dispersion of humanity into distinct nations and language groups. This verse bridges the post-flood Table of Nations with the Tower of Babel event in Genesis 11, illustrating God's sovereign action to scatter peoples and prevent unified rebellion, thereby fulfilling His command to fill the earth through familial lineages that form the ancestors of various ethnic groups.
