Genesis 36:13

And these [are] the sons of Reuel,.... Another son of Esau's; this man had four sons, as follow,

Nahath, and Zerah, Shammah and Mizzah: of whom we know no more than their names, unless Maps or Massa, which Ptolemy z places in Idumea, should have its name from Mizzah:

these were the sons of Bashemath, Esau's wife; her grandsons, as before.
