Genesis 36:42

Duke Kenaz, duke Teman, duke Mibzar,

Genesis 36 is wholly taken up with Esau, that is Edom, and the descendants and nations that sprang from him, on the narrower reckoning almost wholly taken up with the descendants of Esau, who is Edom.
It comes after Jacob meeting Esau in peace, the destruction of Shechem, the revival in Jacob's family when they put away idols and God renewed His promises to Jacob, the death of Rachel and the birth of Benjamin, Reuben's sin, and the account of the sons of Israel.
Then came the death of Isaac at age 180 when Esau and Jacob met for the last time, when Jacob was about 109 years old, Joseph was 17, and Benjamin was a small child two to four years old, ten or eleven years after Jacob's blessing at Peniel.
