Genesis 36:35

And Husham died, and Hadad the son of Bedad, who smote Midian in the field of Moab, reigned in his stead: and the name of his city was Avith.

Aih Avith - i:e., ruins. This royal city has been 'identified with Khurabet el-'Abid (the ruins of 'Abid), in the plain east of Mount Seir, and midway between the two countries here associated with this brief record of Hadad's reign. It is interesting to note that 'Abid, true to its etymology, is situated close to a number of detached hills, forming quite a remarkable group, and at once explaining the origin of the name' (Negeb).
