“These are the kings who reigned in the land of Edom before any king reigned over the Israelites: Bela son of Beor, and the name of his city was Dinhabah” I CHRONICLES 1:43 (The Israel Bible™)

The Book of Chronicles begins with a record of the generations from Adam through the descendants of Yaakov (Jacob). This verse introduces the leaders of the children of Esau, also known as Edom. By listing the heads of the family of Esau, the text confirms that Hashem (God) fulfilled his promise to Rivka (Rebecca) that she and Yitzchak (Isaac) would be the parents of two great nations (Genesis 25:23). Since God promised that both their sons would be become great nations, we are shown that Hashem kept his assurances and blessed Esau, regardless of Esau’s choice to reject God and His covenant. The lesson is obvious. If God even keeps His promise with Esau, who rejected the path of his father Yitzchak, how much more so will Hashem keep His promise to Yaakov, who maintained the covenant.
