Genesis 25:3

And Jokshan begat Sheba and Dedan
Bochart ^F15 is of opinion, that the posterity of this Sheba are the same with the Sabeans who inhabited at the entrance of Arabia Felix, not far from the Nabathaeans; and who, by Strabo ^F16, are mentioned together as near to Syria, and used to make excursions on their neighbours; and not without some colour of reason thought to be the same that plundered Job of his cattle, ( Job 1:15 ) . From Dedan came the Dedanim or Dedanites, spoken of with the Arabians in ( Isaiah 21:13 ) ; Junius thinks Adada in Palmyrene of Syria had its name from this man, and in which country is the mountain Aladan or Alladadan. Bochart ^F17 more probably takes Dedan, a city in Idumea, to derive its name from him. There is a village called Adedi in the country of the Cassanites, a people of Arabia Felix, which Ptolemy ^F18 makes mention of, and seems to have some appearance of this man's name:

and the sons of Dedan were Asshurim, and Letushim, and Leummim;
these names being plural are thought not to be proper names of men, but appellatives, descriptive of their places of abode, or of their business: hence the Targum of Onkelos represents them as such that dwelt in camps, in tents, and in islands; and the Targums of Jonathan and Jerusalem call them merchants, artificers and heads of the people: however, Cleodemus ^F19 the Heathen historian is wrong in deriving Assyria from Asshurim, whom he calls Ashur; since Assyria and Assyrians are so called from Ashur, the son of Shem, ( Genesis 10:22 ) .
