This is the account of the family line of Esau

Genesis 36:1-43

This is the account of the family line of Esau (that is, Edom).

Esau took his wives from the women of Canaan: Adah daughter of Elon the Hittite, and Oholibamah daughter of Anah and granddaughter of Zibeon the Hivite— also Basemath daughter of Ishmael and sister of Nebaioth.

Esau took his wives and sons and daughters and all the members of his household, as well as his livestock and all his other animals and all the goods he had acquired in Canaan, and moved to a land some distance from his brother Jacob. Their possessions were too great for them to remain together; the land where they were staying could not support them both because of their livestock. So Esau (that is, Edom) settled in the hill country of Seir.

These were the kings who reigned in Edom before any Israelite king reigned:

This is the family line of Esau, the father of the Edomites.

Why?

Edomites and Israelites are family born from the same father.

The kings and their cultures is earlier than Israel.

How?

There is no right or wrong, for God's way is beyond my way. The arrangement of the Lord is better than our plans.
