Very cool! It's interesting to note that Methuselah was a contemporary of Adam, that Shem was a contemporary of Methuselah, and Abraham was a contemporary of Shem. According to the Targum and other ancient Hebrew sources, Shem is the Melchizedek mentioned in Genesis 14:18-19. As such, Abraham would have had connections with someone removed by only three generations from Adam and God Himself in the Garden of Eden.
