For pass over the isles of Chittim, and see; and send unto Kedar, and consider diligently, and see if there be such a thing.
Pass over the isles - rather, 'cross over to the isles.'
Chittim ... Kedar - i:e., the pagan nations, West and East, Go where you will, you cannot find an instance of any pagan nation forsaking their own for other gods. Israel alone does this. Yet the pagan gods are false gods; whereas Israel, in forsaking Me for other gods, forsakes their "glory" for unprofitable idols.
Chittim - Cyprus, colonized by Phoenicians, who built in it the city of Citium, the modern Chitti. Then the term came to be applied to all maritime coasts of the Mediterranean, especially Greece (Numbers 24:24; Isaiah 23:1; Daniel 11:30). Kedar - descended from Ishmael, the Bedouins and Arab, East of Palestine.
