According to the author of Chronicles, this verse tells us about the kings who were in charge in a place called Edom before Israel had any kings. The first king mentioned is Bela, and he lived in a city named Dinhabah.
1 Chronicles 1:43: Now these [are] the kings that reigned in the land of Edom before [any] king reigned over the children of Israel; Bela the son of Beor: and the name of his city [was] Dinhabah.
The potential contradiction could relate to the listing of Edomite kings before any king reigned over the Israelites. Some argue this timeline conflicts with other biblical accounts about the establishment of Israelite kings. This may lead to questions about the chronological accuracy and the historical context of when these events occurred according to different parts of the Bible.
