Isaiah 6:3 – “And they were calling to one another: ‘Holy, holy, holy is the Lord Almighty; the whole earth is full of his glory.’”
Extended Explanation of the Verse
Isaiah 6:3 captures the worship of the seraphim around God’s throne. The repeated declaration of “Holy, holy, holy” emphasizes God’s absolute holiness. In Hebrew thought, repetition signifies importance, and saying “holy” three times shows that God’s holiness is beyond compare. This is the only attribute of God repeated like this in the Bible, underscoring its centrality to His character. The phrase “the whole earth is full of his glory” reveals that God’s majesty and presence extend far beyond the temple or Isaiah’s vision—His glory fills all creation.
Historical Context
Isaiah’s vision came during a time of great uncertainty in Judah, following King Uzziah’s death. While the nation may have been focused on earthly challenges, this vision redirects attention to God’s eternal kingship. The seraphim’s song reflects the truth that God’s rule is not limited by human circumstances or geographical borders. Even in times of turmoil, His holiness and glory remain unchanged and pervasive.
Theological Implications
This verse teaches us about God’s holiness, which means He is set apart, perfect, and pure in every way. His holiness is not just one aspect of His character—it defines everything about Him. The fact that His glory fills the earth also demonstrates His omnipresence and sovereignty over all creation. These truths remind us of our smallness before Him and our need for His grace to approach Him.
Literary Analysis
The structure of this verse uses repetition and parallelism to emphasize its message. The threefold “holy” draws attention to God’s supreme holiness, while the declaration of His glory filling the earth balances the focus on heaven with a recognition of God’s work in the world. The seraphim’s call to one another also creates a sense of ongoing, eternal worship, showing that God’s holiness is celebrated continuously.
