This prophecy also is one of the important prophecies telling about Muhammad (Peace be upon him):
Isa 21:13 The burden upon Arabia. In the forest in Arabia shall ye lodge, O ye caravans of Dedanites. Isa 21:14 Unto him that was thirsty they brought water; the inhabitants of the land of Tema did meet the fugitives with their bread. Isa 21:15 For they fled away from the swords, from the drawn sword, and from the bent bow, and from the grievousness of war. Isa 21:16 For thus hath the Lord said unto me, Within a year, according to the years of a hireling, all the glory of Kedar shall fail; Isa 21:17 and the residue of the number of the archers, the mighty men of the children of Kedar, shall be few; for Jehovah, the God of Israel, hath spoken it.
This prophecy tells about the migration of Muhammad (Peace be upon him) from Mecca to Medina with his intimate disciple Abu Bakr, Muhammad(Peace be upon him). The Arab pagans tried to kill Muhammad(Peace be upon him) by swords while he is getting out of his house to migrate, but God blinded them and made them all fall asleep while he gets out, and he passed peacefully. (Ibn Hisham). You can read more about the migration even here:
