John Wesley on Isaiah 21:11

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 between the people and the watchman. 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 - The people are supposed to come to him very early in the morning, to enquire what had happened in the night; which shews a state of great perplexity and fear. Night - The repetition of the words, shew the greatness of their solicitude.
