Isaiah 28:9 Commentary: Prophet's Lament or Scoffers' Mockery?

Isaiah 28 stands in the middle of a series of oracles against the northern kingdom of Israel (Ephraim) and the southern kingdom of Judah. The immediate context is a rebuke of the priests and prophets who have given themselves to wine and strong drink (verse 7). Their drunkenness has affected their judgment: 'They err in vision. They stumble in judgment' (verse 7). This spiritual intoxication leaves them unable to receive God's word.

Into this scene comes the question of verse 9. The people of Judah in the late eighth century BC faced a political and military crisis. The Assyrian empire was expanding, and smaller nations had to choose alliance or submission. The prophet Isaiah consistently urged trust in Yahweh alone, not in foreign alliances. But the leaders found this message too simple, too repetitive. They wanted a more sophisticated political strategy.

The metaphor of weaning is culturally significant. In ancient Israel, children were typically weaned at age two or three, after which they began formal instruction in the family and community. To call someone 'weaned from the milk' was to say they were just past infancy, still needing the most basic lessons. The scoffers use this image to ridicule the prophet: 'Does he think we are kindergarteners?' But the irony is that their own spiritual state is even more immature than a weaned child's. A weaned child is ready to learn; these scoffers refuse to learn at all.

The repetition in verse 10, 'precept upon precept, line upon line', is likely the scoffers' imitation of the prophet's style. They mock his persistent, patient teaching as tiresome and childish. Yet in verses 11-13, God takes their own words and turns them into a judgment: because they would not hear the simple message, he will speak to them through the stammering lips of a foreign conqueror (the Assyrians). The very repetition they mocked becomes the pattern of their destruction.

Another related text is Psalm 131:2, where the psalmist says he has quieted his soul 'like a weaned child with his mother.' There the metaphor is positive, a child who no longer cries for milk but rests content. The scoffers in Isaiah 28, by contrast, are like angry infants who reject the nourishment offered. The difference is not intelligence but humility.

The supplied commentaries and lexical sources note no significant textual variants for this verse. The Hebrew text is stable across manuscripts. The main interpretive difficulty lies in the speaker, not the wording.

Interpreters throughout church history have recognized the sharpness of this verse. Jewish exegesis, represented by Rashi (mentioned in Gill), understood the weaned child as one separated from the law (the milk) and from wise teachers. Early Christian writers such as Jerome emphasized the contempt of the scoffers, seeing in the verse a prophecy of the Jews rejecting the simple gospel. Reformation figures like Calvin used the verse to argue for human inability: even the clearest teaching fails when the heart is proud. Wesleyan commentators (Adam Clarke, Wesley's Notes) followed the reading that the scoffers are mocking the prophet's repetition. In modern preaching, the verse is often used to challenge hearers who think they have outgrown the basics of the faith. The debate over the identity of the speaker persists, but the pastoral application, a call to humility before God's word, remains common across traditions.

Three-point outline

1. The danger of spiritual pride. The scoffers think they are past the need for basic teaching. They consider themselves adults who have outgrown the elementary lessons of faith. Pride makes them unreachable.
2. The patience of God's instruction. Whether this verse is the prophet's lament or the scoffers' mockery, it reveals that God keeps teaching. He repeats his truth, line upon line, because his people keep forgetting.
3. The judgment of being handed over. In verses 11-13, God says he will speak through a foreign tongue. When we reject plain truth, God may use strange circumstances, even harsh ones, to get our attention.

Five-point outline

1. Who is really being taught? The question 'Whom will he teach?' reveals a contest over who needs instruction. The leaders think they don't; the prophet insists they do.
2. The immaturity of the mockers. They call the teaching baby talk, but their own behavior, drunkenness, contempt, rejection of God, proves they are acting like infants who throw tantrums.
3. God's method: repetition. God does not give up. He repeats his word because we are slow to learn. The monotony we complain about is actually mercy.
4. The turning point: judgment as teaching. God's judgment is not just punishment; it is pedagogy. The foreign language of the Assyrians becomes a new lesson, the lesson of consequences.
5. The hope for a teachable heart. Verse 13 ends with destruction, but the chapter is not the last word. The humble remnant, like weaned children, will find rest and refreshing (verse 12).

Illustration hooks

• A coach making the team run the same drill over and over, while the players roll their eyes, thinking they already know it. The coach knows they haven't internalized it yet.
• A parent reading the same bedtime book night after night, even though the child can recite it from memory. The repetition is about relationship, not information.
• A teacher explaining a math concept for the fifth time, and a student muttering, 'I get it already', only to fail the test because they didn't really understand.

Questions your congregation is asking

• 'Why do I get so bored with the Bible? I've heard these stories before.'
• 'How can I tell if my frustration with church teaching is a healthy desire for depth or a sign of pride?'
• 'What does it mean that God will speak "with stammering lips" in my life?'

This passage challenges us to examine our own response to God's instruction. The people in Isaiah's day rejected the simplicity of the prophet's message. How do we react when God's word seems repetitive or too basic? To begin, read Isaiah 28:7-13 together. Then discuss the questions below.

Discussion questions

1. Based on verses 7-8, what was the spiritual condition of the priests and prophets? How did it affect their ability to hear God?
2. Who do you think is speaking in verse 9, the prophet or the scoffers? What clues in the text support your view?
3. Why would the metaphor 'weaned from the milk' be insulting when used by the scoffers, but positive in Psalm 131:2?
4. How does the repetition in verse 10 ('precept upon precept, line upon line') reflect both the people's attitude and God's method?
5. In what ways do we today resist the simple, repeated truths of the gospel? What kind of teaching do we prefer instead?
6. Verses 11-13 show God turning the scoffers' own words into judgment. What does this teach about the seriousness of rejecting God's word?
7. What would it look like for you to become 'like a weaned child' (Psalm 131:2) in your relationship with God this week?
