<p>3:36 <i>The son of Cainan, the son of Arphaxad, the son of Shem, the son of Noah, the son of Lamech</i>- The apparent differences with the genealogy in Gen. 10:24; 11:12; 1 Chron. 1:24 are because Luke is following the Septuagint rather than the Masoretic text. It is common for the New Testament writers to do this. We note that Shem's grandson was called Cainan; clearly there was intermarriage between the descendants of Noah, and the theory that different coloured human beings emerged from the three sons of Noah is simply fantasy.</p>
