Currently, there is a textual debate in creationist circles regarding whether the Masoretic Text (MT) or Septuagint (LXX) preserves the correct chronology in the genealogies of Genesis 5 and 11. Textual criticism gives us the tools to analyze all extant variants to conclude which is most likely original. Critically, the Samaritan Pentateuch gives a third textual tradition that helps reconstruct the textual history of the Genesis 5 and 11 genealogies. This paper will conclude that MT Genesis 5 and 11 is superior to LXX and SP Genesis 5 and 11 from a textual standpoint.
