"A prophecy against Dumah: Someone calls to me from Seir, 'Watchman, what is left of the night? Watchman, what is left of the night?' The watchman replies, 'Morning is coming, but also the night. If you would ask, then ask; and come back yet again.'" NIV translation
Dumah means silence and it is a symbolic word as it is Edom with the "E" removed and Seir means rough or hairy.
This burden is for the descendants of Esau who lived in the area south of the Dead Sea. A watchman was responsible for watching out for danger and alerting a city and we see that Isaiah assumes this title. The people ask the watchman how much longer it will be dark and his reply is that light is coming for some but darkness for others.
This is a reminder to us, as Christians, that the imminent return of Christ will be a wonderful time for us but it will be a time of great darkness and trouble for others. Just as Isaiah assumed the role of watchman with its responsibility, we, too, have the role for the world today. We must warn the people that morning is coming for us but darkness night for those who do not know Jesus Christ.
"A prophecy against Arabia: You caravan of Dedanites, who camp in the thickets of Arabia, bring water for the thirsty; you who live in Tema, bring food for the fugitives. They flee from the sword, from the drawn sword, from the bent bow and from the heat of battle." NIV translation
The Dedanites lived in the northern part of what is known as Saudi Arabia which was just south of Babylon.
They used basic weapons such as the bow but were faced with swords and shields of the Assyrians.
"This is what the Lord says to me: 'Within one year, as a servant bound by contract would count it, all of the splendor of Kedar will come to an end. The survivors of the archers, the warriors of Kedar, will be few.' The Lord, the God of Israel, has spoken." NIV translation
Kedar was the home of nomadic tribes in the Arabian desert and Isaiah warns them that within one year they would be conquered. He says that few will survive and that it is decreed by God.
