Dedan, and Tema, and Buz,.... These seem to be places in Edom or Idumea, of whose destruction Jeremiah prophesies in Jeremiah 49:7; or rather in Arabia and Mesopotamia. Jerom reckons them among the Ishmaelites and Saracens, The persons from whom they descended are mentioned in Genesis 22:21;
and all [that are] in the utmost corners; that is, either of the above countries, or of the whole earth: or "all that had their hair shorn" m; or the corners of their beards; which Jerom says is applicable to the Saracens.
