It reads: Two sons were born to Eber: One was named Peleg, because in his time the earth was divided; his brother was named Joktan.
What do you think the meaning of this passage is? What do you think that it means when it says the earth was divided? What do you think that this refers to? Your thoughts.

25. And to Eber were born two sons: one was named Peleg, because in his days the earth was divided, and the name of his brother was Joktan.
here's the commentary by Rashi...
was divided The tongues became confused, and they were scattered from the valley and were dispersed throughout the entire world. We learn that Eber was a prophet, since he named his son for a future event [i.e. פֶּלֶג resembles the word נִפְלְגָה meaning dispersed.]. And we learned in Seder Olam (ch. 1) that at the end of his [Pelegs] days, they were dispersed. For if you say that [they were dispersed] at the beginning of his days, behold his brother Joktan was his junior, and he begot many families before that, as it is said (verse 26): And Joktan begot, etc., and [only] afterwards, [is it written] (11: 1):And the whole earth was one language. Now if you say [that they were dispersed] in the middle of his [Pelegs] days, [this is not so, because] Scripture does not come to make things obscure but to explain. Hence, you learn that in the year of Pelegs death, they were dispersed.
