From another recent thread I replied in: Most modern-day Jews self -profess to be Ashkenazi, so named because they are descended of Ashkenoz, son of Gomer, son of Noah's son Japeth. The "Children of Israel" with respect to Gods chosen people and the covenant made with Abraham are nowhere in this lineage. Abraham was descended from Noah's first son Shem ("Sem" in Greek, which has no "h", and upon which the word "Semite" is based). You can refer to the first chapter of Mathew or the third chapter of Luke for lineage of Jesus through David back to Shem. Modern-day Jews are NOT the Biblical Israelites, plain and simple, if you use the Bible as authority. If you really wish to drive that point home to a Christian the point can be made that the Christian faith holds that all content of the Bible exists for a point and purpose. For example, nothing further is said about Noah's middle son Ham. Perhaps Japeth's line IS discussed simply to make it clear that the descents of Ashkenoz are NOT descendants of Abraham. Period.
