Isaiah 21:11
11The burden of Dumah. One calls to me out of Seir, “Watchman, what of the night? Watchman, what of the night?”
Wesley: Dumah—of Edom or Idumea. He—the people of Dumah, one of them in the name and by the appointment of the rest. Me—to the watchman: the prophet delivers his prophecy in the form of a dialogue. Seir—out of Edom, which is frequently called Seir. Watchman—the watchman of Edom, whom they had set as people use to do in times of great danger. Night—they come very early to inquire what had happened in the night; which shews a state of great perplexity and fear. The repetition shews the greatness of their solicitude.
Dumah and Seir are Edom, not a twenty-first-century night-watch.
Calvin: the burden of Dumah. It is evident from Genesis 25:14 that this nation was descended from a son of Ishmael. The prophecy is obscure on account of its brevity; yet the Jews needed to be fortified when so many changes took place, that they might not think all things happen by chance. Out of Seir: Mount Seir was a mountain of the Edomites; under this name he includes the whole kingdom. Watchman, what of the night? The Edomites who put the question were solicitous about the danger.
Watchman, what of the night?
Key contrast Both hear Dumah’s call from Seir to a watchman—night-fear. Arminians side with Wesley’s Dumah as Edom or Idumea, a dialogue with Edom’s own watchman. Reformed readers follow Calvin’s further word: Dumah as Ishmael’s line from Genesis 25:14, Seir standing for Edom’s kingdom, the brief oracle given so Judah would not think the shaking of the nations was chance.
