Isaiah 18:1
1Ah, the land of the rustling of wings, which is beyond the rivers of Ethiopia;
Wesley: The Lord—either Ethiopia beyond Egypt; or of Egypt. Wings—the title of wings is given to battlements, to an army, and to the sails of a ship, as this word is here commonly understood. Shadowing with wings is nothing else but overspread or filled with them, in regard of the great numbers either of their armies, or of their ships. Rivers—called rivers in the plural, either for its greatness, or for the many rivulets that run into it. A land beyond the rivers of Ethiopia.
Cush beyond Egypt is a neighbor in the Assyria age.
Calvin: woe to the land. I cannot determine with certainty what is the nation of which Isaiah speaks, though he shews plainly that it bordered on Ethiopia. Some consider it to refer to the whole of Egypt; but this is a mistake, for in the next chapter he treats of Egypt separately. It is not far from Egypt and Ethiopia; some may view it as that part of Ethiopia which lay on the sea-coast, for the Assyrians were at war with the king of the Ethiopians (Isaiah 37:9). Shadowing with wings: its sea was well supplied with harbours, so that it had many vessels and was wealthy.
On this both agree: whirring wings beyond the rivers.
Key contrast Both hear a land beyond the rivers of Ethiopia in the Assyria age. Arminians side with Wesley’s either: Ethiopia beyond Egypt, or Egypt itself, wings as armies or sails. Reformed readers side with Calvin’s further word: not the whole of Egypt, which has its own chapter; a distinct people bordering Ethiopia, perhaps the seacoast of Cush at war with Assyria, though he will not fix the name with certainty.
