Isaiah 21:1
1The burden of the wilderness of the sea. As whirlwinds in the South sweep through, it comes from the wilderness, from an awesome land.
Wesley: The plain—of Babylon, which lay in a very plain country. And the title of the sea might well be given to the waters of Babylon, because of the great plenty and multitude of them. South—in those parts which lay southward from Judea, where there were many and great deserts. Pass through—as meeting with no opposition. Desert—from Media and Persia; a great desert lay between them and Chaldea. A terrible land—from the Medes, a warlike and formidable people. Shared: it comes from the wilderness upon Babylon.
The whirlwind is Media and Persia against Babylon, not a twenty-first-century storm.
Calvin: the burden of the desert of the sea. After teaching that hope ought to be placed not on Egypt but on God’s mercy, he adds consolation: for the Chaldeans, to whom they will be captives, a reward is prepared. By the desert he means Chaldea, not that it was deserted, but because the Jews had a desert on that side of them. As whirlwinds in the south pass through: the destruction will come suddenly from a terrible land.
Chaldea is judged for Judah’s sake. Both readings hold: wilderness, whirlwind, terrible land.
