Boyd’s Bible Dictionary:
(island). Habitable place (Isa. 42:15); island (Gen. 10:5; Isa. 11:11); coast lands (Isa. 20:6; 22:2,6; Ezek. 27:7).
Concise Bible Dictionary:
There are no islands near to Palestine. Cyprus is the nearest, and that is about seventy miles from the nearest point of Syria, far north. So that the term “the isles” may be used at times indefinitely for places or nations far off. We read of “the isles which are beyond the sea,” “the isles afar off,” and “isles of the Gentiles” (Gen. 10:5 and more; Jer. 25:22; Jer. 31:10 and more). It is thought that in some places in the prophets the sea-coasts or maritime countries are intended. Definite islands are also mentioned, especially in the New Testament when Paul began his missionary journeys.
