1 Chronicles 1:53 (KJV)

And when Samlah was dead, Shaul of Rehoboth by the river reigned in his stead.

And when Shaul was dead, Baalhanan the son of Achbor reigned in his stead.

And when Baalhanan was dead, Hadad reigned in his stead: and the name of his city was Pai; and his wife's name was Mehetabel, the daughter of Matred, the daughter of Mezahab.

Hadad died also. And the dukes of Edom were; duke Timnah, duke Aliah, duke Jetheth,

Duke Aholibamah, duke Elah, duke Pinon,

Duke Magdiel, duke Iram. These are the dukes of Edom.
