Isaiah 6

Chapter Text

Isaiah's Commission

Summary

Isaiah presents the parable of the vineyard: the Lord planted a choice vineyard on a fertile hill, hedged it, gathered out the stones, and planted the choicest vine. He built a watchtower and winepress, expecting good grapes, but it brought forth wild grapes. God calls on Jerusalem to judge between Him and His vineyard. He declares He will remove its hedge and wall, making it a wasteland. The vineyard is Israel, and the wild grapes are bloodshed and oppression.

Meaning

The Song of the Vineyard is one of Scripture's most vivid parables of divine judgment. God provided every advantage for His people, yet they produced the bitter fruit of injustice. The wordplay between justice and bloodshed, righteousness and a cry of distress, exposes the gap between God's expectations and Israel's reality.

This parable anticipates Christ's own vineyard parables and His grief over Jerusalem. It teaches that privilege without faithfulness invites severe accountability.

Background

Vineyard imagery was deeply familiar in ancient Judah, where viticulture was a primary agricultural pursuit. The careful preparations described, including terracing, stone removal, and watchtower construction, reflect actual eighth-century farming practices.

The series of woe oracles that follows applies the vineyard parable to specific sins of the ruling class.

Key Verses

“And one cried unto another, and said, Holy, holy, holy, is the LORD of hosts: the whole earth is full of his glory.”— 6:3

The Trisagion — the seraphim's threefold ascription of holiness — is the most exalted declaration of God's transcendent purity in Scripture, echoed in Revelation 4:8 and foundational to Christian liturgy and trinitarian worship.

“Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the LORD of hosts.”— 6:5

Isaiah's cry captures the proper human response to divine holiness: not casual familiarity but trembling self-awareness. It establishes the pattern that true vision of God produces conviction of sin before commission.

“Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then said I, Here am I; send me.”— 6:8

One of Scripture's great missionary texts, often quoted in calls to ministry and evangelism. The plural 'us' has been read by many as an early hint of trinitarian plurality within the Godhead.

People & Places

People

  • Uzziah — King of Judah whose death marks the year of Isaiah's vision, signaling a transition in Judah's history.
  • Isaiah — The prophet who receives this throne-room vision and is commissioned to speak God's word to Judah.
  • Seraphim — Six-winged celestial beings who attend God's throne and proclaim his holiness.

Places

  • The Temple — The Jerusalem sanctuary where Isaiah sees the Lord enthroned, its threshold shaken by the seraphic voice.

Prophecy & Fulfillment

Verses 9-10 contain one of the most frequently cited prophecies in the New Testament, quoted by Jesus to explain his use of parables (Matthew 13:14-15), by John to account for unbelief in Christ (John 12:40), and by Paul at the close of Acts (Acts 28:26-27). The hardening prophecy thus stretches forward to the rejection of the Messiah himself. The promised 'holy seed' remnant in verse 13 also anticipates the faithful stump from which the Branch of Jesse will rise (Isaiah 11:1).

Devotional

Isaiah's vision teaches that genuine encounter with God begins not with usefulness but with awe. Before he is sent, Isaiah is silenced — undone by the holiness he beholds. Only after the coal cleanses his lips does he speak, and then his words are willing surrender: 'Here am I; send me.'

We often want to skip the trembling and rush to the sending. But God's servants are forged in worship before they are dispatched in service. Let the holiness of God expose what needs cleansing in you, and trust that the same altar that convicts also purifies and commissions.

Literary Style

Prophetic call narrative in the form of a throne-room theophany, blending visionary imagery with prophetic dialogue. Features liturgical repetition (the threefold 'Holy'), symbolic action (the burning coal), and a closing oracle in measured Hebrew poetry with vivid agricultural metaphor.
