I found this in my Bible study last week. Very interesting. As Chuck Missler says, "There is nothing in the Bible without a reason."
Genesis 5 Generations of Adam through Noah (Shem, Ham, Japheth)
Genesis 11:10-26 Generations of Shem through Abram.
Genesis 12 God promises a nation to Abram and calls him out of Haran.
Abram was seventy-five years old when he departed out of Haran in the year 2023.
