Introduction
Peleg is a figure in the genealogy of Genesis 11, tracing the line from Shem through Arphaxad to Abraham, recorded as the son of Eber, whose name Genesis connects to the earth being 'divided' in his days.

In the genealogy
Genesis 11 records Peleg's age at the birth of his son and total lifespan, following the same formal pattern used in Genesis 5 for the earlier line from Adam to Noah, though with shorter total lifespans than the pre-flood generations.
The division in his days
Genesis 10:25 states that Peleg's name (related to a Hebrew root meaning "to divide") was given because "in his days the earth was divided", a brief note that later readers have connected variously to the dispersal of peoples after the Tower of Babel or to some other event, without further explanation in the text itself.
