Peleg

Concise Bible Dictionary:

Son of Eber, a descendant of Shem. The name signifies “division,” and apparently he was so called because “in his days was the earth divided” (Gen. 10:2525And 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)). This doubtless means, as is said in Genesis 10:55By these were the isles of the Gentiles divided in their lands; every one after his tongue, after their families, in their nations. (Genesis 10:5), “By these were the isles of the Gentiles divided in their lands”; and again in Genesis 10:3232These are the families of the sons of Noah, after their generations, in their nations: and by these were the nations divided in the earth after the flood. (Genesis 10:32), “By these were the nations divided in the earth after the flood.” In the next chapter is the account of the confusion of tongues and the scattering of the people generally (Gen. 11:16-1916And Eber lived four and thirty years, and begat Peleg: 17And Eber lived after he begat Peleg four hundred and thirty years, and begat sons and daughters. 18And Peleg lived thirty years, and begat Reu: 19And Peleg lived after he begat Reu two hundred and nine years, and begat sons and daughters. (Genesis 11:16‑19); 1 Chron. 1:19, 2519And unto Eber were born two sons: the name of the one was Peleg; because in his days the earth was divided: and his brother's name was Joktan. (1 Chronicles 1:19)
25Eber, Peleg, Reu, (1 Chronicles 1:25)
).
