Genesis 10:25 - Clarke's commentary and critical notes on the Bible

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. Peleg - From פלג palag, to divide, because in his days, which is supposed to be about one hundred years after the flood, the earth was divided among the sons of Noah. Though some are of opinion that a physical division, and not a political one, is what is intended here, viz., a separation of continents and islands from the main land; the earthy parts having been united into one great continent previously to the days of Peleg. This opinion appears to me the most likely, for what is said, Genesis 10:5, is spoken by way of anticipation.
