Contradiction with Genesis 9:24
It suggests Ham is the youngest, implying Shem is older than Japheth.
Genesis 9:24: And Noah awoke from his wine, and knew what his younger son had done unto him.
Paradox #1
Genesis 10:21 involves genealogical details where the lineage of Shem and his relationship to Japheth is described. The contradiction or conflict arises when different translations and interpretations suggest varying accounts of whether Shem or Japheth is the elder brother. This inconsistency is due to differences in ancient manuscript translations and interpretations.
Paradox #2
Genesis 10:21 has a possible numerical inconsistency because it mentions Shem as the older brother of Japheth. However, in another part of the Bible, Shem is often listed after Japheth, suggesting Japheth might be the older brother. This creates some confusion about their birth order.
