The bible book of Isaiah was written by the Prophet Isaiah himself, in Jerusalem , writing was completed in 732 B.C.E. But the total time covered was c.778- after 732 B.C.E. All started from the menacing shadow of the cruel Assyrian monarch hung heavy over the other empires and lesser kingdoms of the Middle East.
The whole areas was alive with talk of conspiracy and confederation.(Isa. 8:9-13) Apostate Israel to the north would soon fall victim to this international intrigue, while Judah’s kings to the south were reigning precariously. ( 2 Ki., chapters 15-21) New weapons of war were being developed and put into action, adding to the terror of the times. ( 2 Chron. 26:14,15)
Where could anyone look for protection and salvation in this distress situation? Although the name of Jehovah was on the lips of the people and the priest in the title kingdom of Judah, their hearts turned far off in other directions, first to Assyria and then down to Egypt. ( 2 Ki. 16:7; 18:21). Their faith in Jehovah power waned. Where it was not outright idolatry, there prevailed a hypo-critical way of worship,based on formalism and not the true fear of God.
Who then would speak for Jehovah saving power to turn the hearts of he Israelite back to Jehovah. Well said by one Prophets called Isaiah, he said ” Here i am! Send me.” It was the year that leprous King Uzziah died, about 778 B.C.E. 9 ( Isa. 6:1, 8) The name of Isaiah means ” Salvation of Jehovah,” which is the same meaning, though written in the reverse order, of the same name Jesus (” Jehovah is Salvation”). From beginning to finish, Isaiah’s prophecy highlights this fact, that Jehovah is Salvation.
Who then was Isaiah? Isaiah was the son of Amos ( not to be confused with Amos, another prophet from Judah). ( Isaiah 1:1) The scriptures are silent to his birth and death, though Jewish tradition has him saw as under by wicked King Manasseh. Compare the scripture in Hebrews 11: 37.) His writing show him, stationed in Jerusalem with his prophetess wife and at least two sons with prophetic names ( Isa. 7:3; 8: 1, 3)
He served during the time of at least four Kings of Judah namely; Uzziah, Jothanm, Ahaz, and Hezekiah; evidently beginning about 778 B.C.E. ( When Uzziah died, or possibly earlier) and continuing at least till after 732 B.C.E. ( Hezekiah’s 14th year), or no than 48 years. No doubt that he had also committed his prophecy to writing by this latter date. ( 1:1; 6:1; 36:1) There were other prophets during his day namely: Micah in Judah and, to the north, Hosea and Obed.
( Micah 1:1; Hos. 1;1; 2 Chron. 28:6-9). The one ordered Isaiah to write down his prophetic judgements were Jehovah say ” Isaiah 30:8: ” Now, come it upon a tablet with them, and inscribe it even in a book, that it may served for the future day, for a witness to time indefinite .” The ancient Jewish rabbis recognized Isaiah as the the writer and included the book as the first book of the major prophets (Isaiah, Jeremiah, and Ezekiel).
