Isaiah

The book of Isaiah is the third longest in the Bible, after Jeremiah and Psalms.^[1] It is also the most frequently cited Old Testament book in the New Testament, with 194 passages that quote or allude to it. These references cover 54 of Isaiah’s 66 chapters.^[2] Due to its deep insights into the person of Christ, some scholars have called Isaiah the “fifth gospel.”

Authorship

Isaiah may have been an aristocrat, because it was easy for him to access the kings of Israel (Isa. 7:3; 37:21-22). At the same time that Isaiah was serving as a prophet, Amos and Hosea prophesied in the North, and Micah prophesied in Judah. Isaiah prophesied almost exclusively in Jerusalem—over at least a 34-year span.

He served from 740 BC to 687 BC, through the reigns of King Uzziah (~740 BC) to King Hezekiah (~716-687 BC). Uzziah’s reign was peaceful, because the Assyrians were dormant at this time. Later, however, three kings were more ambitious in attacking Judah (e.g. Shalmaneser, Sargon II, and Sennacherib). The Jewish kings had to deal with these military forces, and Isaiah served as a spiritual counselor to multiple kings throughout this turbulent period in Israel’s history. Because of Isaiah’s influence, the southern kingdom (Judah) lasted a full 100 years longer than the northern kingdom (Israel).

Authorship of Isaiah. While the book of Isaiah claims to be written in the 8^th century B.C. (739-681 B.C.) by “Isaiah son of Amoz” (Isa. 1:1; 2:1; c.f. Is. 7:3), higher critics of the OT claim that it was written in multiple parts by multiple people (“Second Isaiah” and “Third Isaiah”). We reject this spurious view.

Audience

Isaiah’s audience was primarily Judah and Jerusalem (Isa. 1:1). However, he also addressed the surrounding Pagan nations (see chapters 13-23, 46-48). During the time that Isaiah wrote this book, Assyria was in power, reigning from 900 to 609 BC.

It’s easy for the reader to trust in God when reading the book, but picture yourself there at the time. John Oswalt writes, “The nation of Assyria was the single most prominent force, both politically and militarily, in the ancient Near East.”^[3] Imagine trying to trust God’s word and his prophet when the Nazi’s were looming on the horizon—ready to invade. It would have been frightening to trust God in this era of history, as the fiercest army known to man was ready to invade borders of Israel.

Main Outline of Isaiah

Israel is not God’s Servant (Isaiah 1-5). Isaiah opens his book demonstrating that the nation of Israel is not God’s Servant (see “The Servant Songs”). The nation is filled with sinful unbelief. Isaiah uses the language of a court of law to describe God’s indictment of the nation—what has been called a pretrial “arraignment” where the prosecution reads the charges and the defendant gives his plea.^[4] This introduction explains why God would judge the nation.

God calls Isaiah as a prophet (Isaiah 6). Before Isaiah explained his calling, he wanted to show the depravity of Israel and the dire circumstances that led him to come to God. Without this historical backdrop, Isaiah’s calling wouldn’t have made as much sense. When we understand the sinfulness of Israel and the sinfulness of Isaiah himself (Isa. 6:5), it makes God’s calling all the more gracious.

How will God respond to the wicked nation? He describes the coming of the future Messiah, who will one day bring justice to the nation and the world (Isaiah 7-12). Earlier, Isaiah illustrated the nation’s corruption (chs. 1-5), and he also acknowledged his own shortcomings (ch. 6). The question then arises: who can rescue the nation? Chapters 7 through 12 form a cohesive literary unit that answers this question.

A clue is offered at the close of Isaiah 6: “The holy seed will be the stump in the land” (Isa. 6:13). In this section, Isaiah begins to unfold more details about the coming “seed”—the King Messiah—who will bring restoration.

Isaiah starts by describing the miraculous birth of this figure, leading the people to call him “God is with us” (Isa. 7:14). He then identifies this figure as “Mighty God” (Isa. 9:6-7), and ultimately, he foretells that this figure will establish God’s kingdom on Earth (Isa. 11). Throughout these chapters, the portrait of the Messiah emerges step-by-step, offering the solution to the nation’s woes presented in chapters 1-6.

After describing his glorious messianic kingdom, God describes how all other kingdoms will fall under his judgment (Isaiah 13-23). In Isaiah’s day, the Assyrian King Sennacherib cast his frightening shadow over the city of Jerusalem. Sennacherib had already conquered the northern nation of Israel. With Assyria banging on the gates of Jerusalem, it would be tempting to turn to the surrounding military powers for help in fighting Assyria.

Wrong move. Isaiah argues that it is foolish and futile to look to these nations for help, when God is going to judge them as well. This military and political background becomes clear in the narratives of Ahaz’s failure (Isa. 7) and Hezekiah’s success (Isa. 36-39). Ahaz refuses to trust in God’s help, while Hezekiah is a king who trusts God. Through these narratives, we learn that lesson that God is the only true source of protection.

God will judge the nations in the short term (Isaiah 13-23), and he will judge the world in the long term (Isaiah 24-27). This section has been called “Isaiah’s Apocalypse,” because Isaiah describes the end of the world. Indeed, the only mention of a local territory refers to Mount Zion and Jerusalem (Isa. 24:23). God will judge kings as well as angels and demons in this final judgment (Isa. 24:21).

Isaiah returns to the military crisis facing Judah. With the looming threat of Assyria at the gates of Jerusalem, will the people turn to Egypt or to God? (Isaiah 28-35) After giving a description of the end of the world and the ultimate destruction of the pagan nations, Isaiah writes a polemic against trusting in these nations. He continues to dismantle the desire to trust in these surrounding nations. These chapters “should be considered a subunit within the long literary unit that began in 13:1.”^[5]

The “key issue in chapters 28-35 is whether Judah, and in particular its leaders, will rely on Egypt or on the Lord in the face of the growing threat posed by the ever-increasing power of Assyria.”^[6] In the center of this section, Isaiah writes, “Woe to those who go down to Egypt for help, who rely on horses, who trust in the multitude of their chariots and in the great strength of their horsemen, but do not look to the Holy One of Israel, or seek help from the LORD” (Isa. 31:1).

Hezekiah’s battle of belief (Isaiah 36-39). Isaiah pauses his prophetic message to include several chapters of narrative, following a pattern he established earlier in chapters 6-7 and 20. This moment has been foreshadowed throughout the entire book.

In these chapters, Isaiah details the advance of Sennacherib—king of Assyria—as he moves to attack Judah. How will Hezekiah—the king of Judah—will respond to this real and present danger of Assyria? For those familiar with the unfolding story, the anticipated answer seems clear: “Trust in God!” Yet, the tension remains: Will Hezekiah waver in the face of this looming crisis (like Ahaz in chapter 7) or will he stand firm in faith?

Hezekiah almost listened to his court advisors instead of Isaiah. But, in the end, Isaiah’s counsel—much of which is in this section—talked some theological sense into the mind and soul of the great king. These chapters are almost identical to 2 Kings 18-20. It is unclear of who borrowed from whom—though Grogan (p.223) and Webb (p.156) hold that Isaiah wrote this first.

After the exile, the Jewish people needed encouragement from God (Isaiah 40-48). Chapter 39 ended on an ominous note: Isaiah predicted to Hezekiah that Babylon would plunder Judah and make Hezekiah’s heirs eunuchs. All of this happened during the Babylonian Exile.

Imagine being an ancient Jewish person living after the Babylonian Exile. In the ancient world, people believed that their gods would win wars for them. Because the Babylonians overtook Judah, the people must’ve thought that God had either abandoned them or that he wasn’t as powerful as the foreign deities. This explains why Isaiah goes to great lengths to explain how all idols are worthless, and God is the only true God (Isa. 45:5). This section has been called, “The Battle with the False Gods.”

God will heal the nation and the world through his Servant (Isaiah 49-55). In chapters 40-48, the people of Israel are called God’s “servant.” However, they don’t act like God’s servant to the nations. They still bring accusations against God and doubt his goodness. In this section, God reveals his true “Servant” who will bring the nations to faith in Yahweh.

God will rule the world (Isaiah 56-66). Isaiah predicted the rise of the Messiah in chapter 7-12, and he predicted the rise of the Servant in chapters 42-53. As it turns out, this is the same person: Jesus Christ. In this final section, he rules and reigns on Earth, inaugurating the Millennium and the New Heavens and Earth.

Isaiah uses the language of a court of law to describe God’s indictment of the nation—what has been called a pretrial “arraignment” where the prosecution reads the charges and the defendant gives his plea.^[7] This introduction explains to the reader why God would judge the nation.

Consulted Commentaries

Barry Webb, The Message of Isaiah: On Eagles’ Wings, ed. J. A. Motyer and Derek Tidball, The Bible Speaks Today (England: Inter-Varsity Press, 1996).

This short commentary (~250 pages) does an extremely good job at explaining the big picture of the book. It doesn’t get into great detail. Rather, it helps the reader see the big picture. We disagree with Webb’s replacement theology of Israel with the Church, but otherwise, this is a highly recommended commentary for anyone studying Isaiah.

J. A. Motyer, The Prophecy of Isaiah: An Introduction & Commentary (Downers Grove, IL: InterVarsity Press, 1996).

Motyer is a scholar and specialist of Isaiah. He has written several commentaries on this book, including one for Tyndale and a devotional commentary called Isaiah by the Day: A New Devotional Translation (2014). We have only read his longer commentary that is 544 pages in total—on average, 8 pages per chapter. This commentary moves at a quick pace, while also relying on Motyer’s training in the original languages and the Old Testament context. We highly recommend this commentary.

He holds to an Amillennial or Historical Premillennial view—perspectives that are difficult to tell apart.

We appreciated Motyer’s wholistic approach to Isaiah, incorporating the New Testament as well as sound exegesis. This commentary is going to err on the side of seeing Jesus throughout this book, but we see no problem with this approach. This was refreshing to read after studying Gary Smith’s commentary, which seldom moves beyond the text of Isaiah or even to the Old Testament in general.

Geoffrey W. Grogan, “Isaiah,” in The Expositor’s Bible Commentary: Isaiah, Jeremiah, Lamentations, Ezekiel, ed. Frank E. Gaebelein, vol. 6 (Grand Rapids, MI: Zondervan Publishing House, 1986).

Grogan holds to a premillennial view, and his study is a good beginning commentary on Isaiah. It is roughly 350 pages—or roughly 5 pages of commentary per chapter of Scripture.

Gary V. Smith, Isaiah 1-39, ed. E. Ray Clendenen, The New American Commentary (Nashville: B & H Publishing Group, 2007).

Gary Smith, Isaiah 40-66, vol. 15B, The New American Commentary (Nashville, TN: Broadman & Holman Publishers, 2009).

Smith’s commentary on Isaiah is a technical and rigorous work, spanning approximately 1,400 pages—or roughly 20 pages of commentary per chapter of Scripture. He takes Isaiah at face value, rarely citing the New Testament to support his views. While he is a conservative theologian, he prioritizes studying the text of Isaiah itself before referencing other scriptures.

This methodology has both strengths and weaknesses. On the positive side, it encourages the interpreter to focus directly on the text rather than turning to external passages. However, a drawback is that it limits the interpretation to Isaiah alone, whereas a more holistic approach, incorporating all of Scripture (tota Scriptura), can provide a fuller understanding. Smith’s conservative theology, which upholds verbal plenary inspiration, is evident throughout his commentary, though his approach tends to exclude direct engagement with the New Testament.

Smith’s interpretation reflects a premillennial viewpoint. Regarding Isaiah 65:18, He writes, “God’s new creation will include nature, the nations, the Israelites, Jerusalem, and the temple.”^[8] However, he says nothing about the existence of a Millennium—never using the word. Moreover, his treatment of Isaiah 65:20 was lacking. Under his view, the presence of death is a “hypothetical situation drawn from life in this sinful world,” and it is used to “illustrate the point that people will live a very long time.”^[9]

While this commentary has many advantages, its main drawback is its excessive detail. The page count could’ve been cut in half without resulting in much lost. In fact, the work is even lengthier than John Oswalt’s comprehensive technical commentary on Isaiah (which is no small feat!).
