1 Chronicles 1:43 (ESV)
These are the kings who reigned in the land of Edom before any king reigned over the people of Israel: Bela the son of Beor, the name of his city being Dinhabah.
1 Chronicles 1-4 is like reading an old phone book or computer data based for residents in a certain area. It is almost entirely names and linages. There are times the Chronicler’s pen, however, gives way to some nugget of interest concerning a certain person(s) listed. For instance read here:
1 Chronicles 1:10 (ESV)
Cush fathered Nimrod. He was the first on earth to be a mighty man.
In the above verse we have a significant change in the Chronicler’s approach. Although the entire four chapter are about the linage of Judah, from all the way back to Abraham’s day, the Chronicler inserts the above mention of Esau (Edom), Jacob’s twin, but older brother. Remember how this was laid out in Scripture:
Romans 9:13 (ESV)
As it is written, “Jacob I loved, but Esau I hated.”
God, in HIs divine sovereignty, chose Jacob (the younger) over Esau (the older). In the traditions of that day, the older son would get all the inheritance. So as the Chronicler is laying out the ancestry of Judah (for the purpose of identifying the kingly line of David ... the theme for the rest of the book). In doing this work he takes time to mention who is not in the line of kingship. He is pointing out that the kings of Esau were replaced by this long list of kings of Judah, the descendents of Jacob.
It is importnat to realize that even though this might be just a list of names to us, to God is shows His sovereign will over generations. It shows He has established Judah as His people. It shows He is not only honoring the covenant He made with Abraham, but how He was honoring it. God is sovereign and puts up on and takes down another. It is His choice.
Psalms 75:7 (ESV)
but it is God who executes judgment,
putting down one and lifting up another.
