Isaiah 21: 13-15. ” The burden upon Arabia. In the forest in Arabia shall ye lodge, O ye travelling companies of Dedanim. The inhabitants of the land of Tema brought water to him that was thirsty, they prevented with their bread him that fled. For they fled from the sword, and from the bent bow, and from the grievousness of war.”
There are no great forests of trees in Arabia, but there is very thick underwood making some places very rugged and inaccesible.
The traveling companies are caravans, or roving tribes of Arabs.
The Dedanim are descendants of Dedan, son of Abraham by Keturah (Gem. 25:31).
Tema is also a descendant of Abraham through Hagar and Ishmael ( Gen. 25:15).
This passage is the story of one group of people helping others who are traveling to escape the bloodshed of the Assyrian armies. Water and food were offered to them as they traveled and hid.
