There is also an important redemptive-historical development from Isaiah to Jesus. John 12:41 explains that Isaiah “saw his glory and spoke of him.” This means either that the prophet saw the glory of the preincarnate Messiah, who is “high and lifted up” (Isaiah 6:1), or that he foretold the exaltation of the suffering servant, who reveals God’s glory as he accomplishes God’s redemptive plan (Isaiah 52:13–53:12). In either interpretation, Jesus is not merely another messenger from God but the glorious God-in-the-flesh, “full of grace and truth” (John 1:14). He is both the fulfillment of the rejected-prophet pattern and the one foretold by the prophets.

Isaiah 6 recounts one of the most stunning revelations of God’s majesty in the Old Testament. The prophet writes, “In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and the train of his robe filled the temple” (Isaiah 6:1). The six-winged seraphim — fiery, flying heavenly beings — call to one another with booming voices, “Holy, holy, holy is the Lord of hosts; the whole earth is full of his glory!” (Isaiah 6:3).

Isaiah responds to this awesome theophany with distressed confession: “Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the Lord of hosts!” (Isaiah 6:5). One of the fiery angels touches Isaiah’s mouth with a coal from the heavenly altar to remove his guilt, and then the Lord calls and commissions his prophet. Isaiah’s initial zeal — “Here I am! Send me” (Isaiah 6:8) — turns to confusion — “How long, O Lord?” (Isaiah 6:11) — when the prophet considers his challenging charge:

Go, and say to this people: “Keep on hearing, but do not understand; keep on seeing, but do not perceive.” Make the heart of this people dull, and their ears heavy, and blind their eyes; lest they see with their eyes, and hear with their ears, and understand with their hearts, and turn and be healed. (Isaiah 6:9–10)

While Revelation 4 recalls Isaiah’s vision of the divine throne, Jesus and the apostles more frequently cite the prophet’s commission to preach to a recalcitrant people unable to hear or see spiritual truths. These verses feature prominently in all four Gospels (Matthew 13:13–15; Mark 4:12; Luke 8:10; John 12:39–41), the book of Acts (Acts 28:25–28), and even Paul’s letter to the Romans (Romans 11:8). Why? This Old Testament passage helps to explain how the rejection of Jesus and his followers fulfills the larger biblical pattern of the maligned messengers of God.

Let’s review the context of Isaiah’s prophecy and then consider Jesus’s use of this passage in Matthew 13:13–15.

Isaiah’s Startling Commission

Isaiah 1–5 establishes Judah’s chronic idolatry, hardness of heart, and lack of spiritual understanding. Though there are flickers of hope about what God will do “in the latter days” (Isaiah 2:2–5), these chapters repeatedly expose the people’s rebellion and announce God’s coming reckoning. The people are like unruly children who have despised the Holy One of Israel (Isaiah 1:2–4). In their idolatry and immorality, Judah resembles Sodom and Gomorrah, the wicked cities God destroyed with fire and brimstone (Isaiah 1:9–10). The beloved vineyard of the Lord has yielded nothing but wild grapes (Isaiah 5:1–7).

For five tense chapters, Isaiah decries their sins and warns of judgment. Then, in chapter 6, Isaiah beholds God’s glory and receives his commission to blind the people’s eyes, stop up their ears, and harden their hearts (Isaiah 6:9–13). The prophet’s preaching would not merely warn the people but would confirm them in their stubborn rebellion against God.

The biblical prophets often speak of Israel’s malfunctioning eyes and ears to illustrate their inability to respond rightly to divine revelation. This imagery reflects God’s earlier word of judgment in Deuteronomy 29:4: “To this day the Lord has not given you a heart to understand or eyes to see or ears to hear.” Moreover, pronouncements about the people’s spiritual blindness, deafness, and dullness reveal that they now resemble the lifeless idols they have revered. Psalm 115:4–8 unpacks this biblical logic.
