Commentary on Isaiah 28

Isaiah 28 is a prophetic courtroom scene where God, through Isaiah, confronts the drunken leaders of Ephraim (the northern kingdom) and then the scoffing rulers of Judah. The chapter moves from a specific judgment on Samaria’s pride to a broader indictment of Jerusalem’s complacent leadership, who have made a covenant with death. In the midst of judgment, Isaiah lays a cornerstone of hope: God himself will establish a precious foundation in Zion. The chapter is a stark warning against spiritual intoxication—whether from wine or from self-reliance—and a call to trust in God’s strange, alien work of judgment that clears the way for grace.

Historical context

Isaiah ministered during the reigns of Uzziah, Jotham, Ahaz, and Hezekiah (roughly 740–700 BC). Chapter 28 is set against the backdrop of the Assyrian threat. The northern kingdom of Israel (Ephraim) was in its final years, and Samaria, its capital, would fall to Assyria in 722 BC. The drunkenness of Ephraim’s leaders (v. 1) is both literal and metaphorical—a picture of spiritual stupor and political folly.

Judah, meanwhile, was tempted to rely on Egypt for military aid rather than on the Lord. The leaders of Jerusalem had made a “covenant with death” (v. 15), likely a political alliance they thought would protect them from Assyria. Isaiah exposes this as a lie. The chapter also contains one of the Old Testament’s clearest messianic prophecies: the cornerstone laid in Zion (v. 16), which the New Testament applies to Christ (Rom 9:33, 1 Pet 2:6). The historical situation is thus a crisis of trust: will God’s people rely on him or on human schemes?

Verse by verse

• 1:

  The chapter opens with a woe against the “proud crown of the drunkards of Ephraim.” Samaria, the capital of the northern kingdom, sits on a hill like a garland of flowers—beautiful but fading. The leaders are drunk, both literally and spiritually. Their intoxication symbolizes a lack of discernment, a refusal to see reality. The judgment is sure: the crown will be trampled underfoot.

• 5:

  Suddenly, the tone shifts. In that day, the Lord of hosts himself will become a “crown of beauty” for the remnant of his people. The contrast is deliberate: human glory fades and is trampled; divine glory endures and adorns. This verse anticipates the remnant theology that runs through Isaiah—God always preserves a people for himself, not because of their merit, but because of his grace.

• 7:

  The indictment widens to include Judah. Priests and prophets stagger from wine and strong drink. They are “swallowed up” by alcohol, reeling in visions and stumbling in judgment. This is not merely a temperance lecture; it is a diagnosis of spiritual incapacity. Those who should be the clearest-eyed guides for God’s people are the most disoriented. The table of the Lord has become a place of vomit and filth.

• 10:

  The drunkards mock Isaiah, reducing his message to childish babble: “Precept upon precept, line upon line, here a little, there a little.” They treat God’s word as a tedious, repetitive lecture. But Isaiah turns their mockery back on them: because they refuse to hear, God will speak to them through the strange tongue of the Assyrian invaders. What they dismissed as baby talk will become the terrifying language of an occupying army.

• 12:

  God had offered them rest and repose—a quiet trust in him. But they would not listen. The tragedy is not that God was silent, but that he spoke and they refused to hear. The word for “rest” (menuchah) echoes the rest of the Promised Land (Deut 12:9) and the Sabbath rest. Their refusal to trust God means they will find no rest, only the relentless march of Assyrian soldiers.

• 14:

  Isaiah addresses the “scoffers” who rule in Jerusalem. These are not ordinary sinners but leaders who treat God’s warnings with contempt. They have made a covenant with death and an agreement with Sheol, believing that when the Assyrian flood comes, it will not reach them. This is almost certainly a reference to a political treaty with Egypt, which they trusted more than the Lord.

• 16:

  This is the theological heart of the chapter. God declares that he is laying in Zion a foundation stone, a tested stone, a precious cornerstone, of a sure foundation. The one who believes will not be in haste—or, as the Septuagint renders it, will not be put to shame. This stone is Christ himself (Rom 9:33, 1 Pet 2:6). Human alliances are shifting sand; God’s Messiah is the only sure foundation. Faith in him is the opposite of frantic self-preservation.

• 17:

  God will use justice as a measuring line and righteousness as a plumb line. The cornerstone is not only a place of refuge but also a standard of judgment. Those who reject it will find that their refuge of lies is swept away by the hail and flood they thought they had escaped. The covenant with death is annulled; the agreement with Sheol does not stand.

• 21:

  God’s work of judgment is described as “alien” and “strange.” He will rise up as at Mount Perazim (2 Sam 5:20) and the valley of Gibeon (Josh 10:10-11)—places where he fought for Israel. Now he fights against them. This is the terror of the gospel: the same God who saves is the God who judges. His work of judgment is foreign to his nature (he is slow to anger), but it is necessary because of sin.

• 23:

  The chapter ends with a parable about farming. The farmer does not plow forever; he eventually sows. He does not thresh all crops the same way—dill is beaten lightly, cumin is struck with a rod, but bread grain is crushed more thoroughly. The point: God’s judgments are measured and purposeful. He knows what he is doing. His discipline is not random destruction but preparation for harvest. This is a word of hope hidden inside a word of warning.

Application

Isaiah 28 confronts us with a question: where are we placing our trust? The leaders of Jerusalem had made a covenant with death—a political alliance they thought would save them. We do the same when we trust in money, reputation, military power, or even religious activity to secure our future. The chapter calls us to stop building on sand and to build on the cornerstone God has laid in Zion.

But there is also a gentler word here. The farmer knows how to thresh each crop. God’s discipline in your life is not random cruelty; it is measured wisdom. He knows exactly what pressure is needed to produce fruit, not to destroy you. If you are under his hand today, do not despise it. He is preparing a harvest. And the cornerstone—Jesus Christ—is the only foundation that will hold when the flood comes. Believe in him, and you will not be in haste.
