Contradiction with Genesis 11:9
This verse describes the scattering of people over the earth after the events of the Tower of Babel, suggesting a timeline after Genesis 10:32, although Genesis 10:32 implies a division had already occurred.
Genesis 11:9: Therefore is the name of it called Babel; because the LORD did there confound the language of all the earth: and from thence did the LORD scatter them abroad upon the face of all the earth. [Babel: that is, Confusion]
Contradiction with Acts 17:26
This verse states that God made all nations from one blood and determined their times and the bounds of their habitation, suggesting a more unified origin than implied by the separate clans of Genesis 10:32.
Acts 17:26: And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation;
Contradiction with Genesis 10:5
Earlier in the same chapter, this verse mentions the division of nations by languages, seemingly contradicting the implication that division happened later as described in Genesis 10:32.
Genesis 10:5: By these were the isles of the Gentiles divided in their lands; every one after his tongue, after their families, in their nations.
