Easton's Bible Dictionary (1897)
(Obad. 1:20), some locality unknown. The modern Jews think that Spain is meant, and hence they designate the Spanish Jews “Sephardim,” as they do the German Jews by the name “Ashkenazim,” because the rabbis call Germany Ashkenaz. Others identify it with Sardis, the capital of Lydia.
Smith's Bible Dictionary (1863)
(separated), a name which occurs in (Obadiah 1:20) only. Its situation has always been a matter of uncertainty.
Hastings' Dictionary of the Bible (1898) & Schaff's Bible Dictionary
SEPH'ARAD (separation), a place from whence captive Jews would return to the cities of the South. It is named only in Ob 20. Some identify the place with Sardis in Lydia; others with Zarephath; while modern Jews regard it as Spain, and others identify it with Sipphara. See Sepharvaim.
