The Sons of Javan

ElishahJosephus says they are “now the Aeolians,” on the northern part of the Aegean coast of Turkey. The ESV and Holman both put them on Cyprus.
TarshishThe location of “Tarshish,” in the Bible, is famously unknown, but Josephus confidently has it as Cilicia, the capital of which was Tarsus, on the southeast coast of Turkey. The ESV speculates it is Tartessos in Spain, while Holman says that it is in Italy, or some point thereabout.
KittimAll agree that Kittim is Cyprus.
DodanimReading “Rhodanim,” ESV and Holman have this as Rhodes; Josephus does not mention it.

Note: these two latter groups together also make seven in number.
