Mezahab
Me-zahab appears only as a maternal great-grandfather in the Edomite king-list, mentioned twice in identical wording across the parallel registers in Genesis and Chronicles. He is named for the sake of locating Mehetabel, the wife of the Edomite king Hadad, in her female line.
In the Edomite king-list
Genesis records his place at the close of the list of kings who reigned in Edom: "And Baal-hanan the son of Achbor died, and Hadad reigned in his stead: and the name of his city was Pau; and his wife's name was Mehetabel, the daughter of Matred, the daughter of Me-zahab" (Ge 36:39).
The Chronicler reproduces the same notice with a slight variation in the spelling of the royal city: "And Baal-hanan died, and 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 Me-zahab" (1Ch 1:50).
In both notices Me-zahab is reached only by tracing back through Mehetabel and her mother Matred — three generations of women named in succession, an unusual concentration of female lineage within the king-list.
