Question

"The burden upon Arabia. In the forest in Arabia shall ye lodge, O ye travelling companions of Dedanim. The inhabitants of the Land of Tema brought water to him that was thirsty, they prevented with their bread him they fled. For they fled form the swords, from the drawn swords and from the bent bow, from the grievousness of war. For thus hath the Lord said unto me, within a year, according to the years of a hireling, and all the glory of Kedar shall fail; And the residue of number of archers, the mighty men of the children of Kedar, shall diminished: for the Lord God of Israel hath spoken it." (Isaiah 21:13-17)

Answer 1

The first point to bear in mind in connection with this prophecy is that Arabia is the scene of the Prophecy. This is most significant. Hadhrat Muhammad appeared in Arabia.

Secondly, the prophecy speaks of "Him that fled". The flight of Hadhrat Muhammad is momentous event in the history of the world. It is upon the flight of Hadhrat Muhammad from Mecca that the Muslim calendar begins.

Thirdly, "fled from drawn swords" conclusively proves the fulfillment of the prophecy in Hadhrat Muhammad who fled from Mecca when his house was surrounded by his deadly enemies who stood there, drawn swords in had, thirsty for his blood.

Fourthly, another clear testimony in favor of Hadhrat Muhammad is found in: "within a year... all the glory of Kedar will fail... the mighty men of Kedar shall diminish." This was fulfilled in the battle of Badr which occurred within a year from the flight of Muhammad, and in which battle, the Quraish of Mecca (Kedar) sustained a crushing defeat; most of their mighty men fell.

Rev. C. Forster locates the Kedar in Hedjaz and identifies them with Koraish. See: The Historical Geography of Arabia by Rev. C. Forster, pp. 244-265.

Answer 2

It appears to be a prophecy against the land of Arabia in the days of Isaiah. Probably the enemy being referred to were the Assyrians, who were the dominant power at the time. The Dake's commentary on the Bible defines Arabia as "a large country south of Syria and Trans-Jordan, west of Euphrates and the Persian Gulf, north of the Red Sea and east of Palestine."
The Dedanim were descendants of Dedan, son of Abraham by Keturah; Tema and Kedar are descendants of Ishmael.

Answer 3

v. 13 " The burden upon Arabia refers to the various Arabian tribes of the desert beyond Edom. Dedanim refers to Dedan, a region in Arabia. Tema was an oasis where Nabonidus spent much of his time while his son Belshazzar ruled over Babylon. Kedar is a tribe of Ishmaelite descent. The prophet predicts that these desert tribes will be no match for the coming Assyrian invasion."

v 14 "The valley of vision refers to Jerusalem, located on the hills surrounded by dominating mountain ranges. The gathering storm of judgment will dump its greatest torrents on Jerusalem herself. The coming Babylonian invasion will cause the people to go up to the housetops to observe the siege of the city. Kir and Elam are pictured as mercenaries of Babylon. The choicest valleys, which had known the blessing of prosperity, will then be full of chariots of the invading army. The prophet calls for weeping, mourning, and sackcloth (repentance), but instead the people have developed the attitude of eat and drink; for tomorrow we shall die."

v 15 -25 "Shebna is referred to as the treasurer and apparently was the leader of the pro Egyptian faction in Jerusalem. Thinking his position was secure, he had already ordered a large sepulcher (tomb) to be raised in his memory. Instead, Isaiah predicts that he will soon be demoted and will eventually die a pauper in a foreign country. Shebna was replaced by Eliakim during the reign of Hezekiah, as indicated in 2 Kings 18:18. The key of the house of David refers to the responsibility of protecting the Davidic line."

Answer 4

It refers to arabia falling to Nebuchadnezzar and the Babylonians. I hope you don't think it refers to Mohammad conquering arabia because it says it will happen "within a year" and that was back in around 600BC.
