What does Isaiah 27:2 mean?
What is the meaning of Isaiah 27:2?

In that day

• Isaiah often uses this phrase to point beyond his own lifetime, zooming in on the climactic moment when the LORD personally intervenes in history (Isaiah 2:11; 11:10; 25:9).

• It signals a time of restoration, not wrath—unlike the earlier oracles of judgment (Isaiah 24). Romans 11:26 echoes this day when “all Israel will be saved,” showing the continuity of God’s plan.

• By anchoring the promise to a specific future day, God underscores His covenant faithfulness: what He foretells, He will fulfill (Numbers 23:19).


Sing

• Worship is the first response God desires when He redeems His people. The command recalls “Sing to the LORD a new song” (Psalm 98:1) and Isaiah 12:5, “Sing praises to the LORD, for He has done glorious things.”

• Singing unifies the redeemed community (Ephesians 5:19) and proclaims God’s glory to the nations (Psalm 96:3).

Revelation 5:9 shows heaven itself breaking into song over the Lamb’s victory, previewing how earth is to echo heaven “in that day.”


A fruitful vineyard

• Israel was once “the vineyard of the LORD” that yielded only “wild grapes” (Isaiah 5:1-7). Now God reverses the failure: “I, the LORD, am its keeper; I water it continually” (Isaiah 27:3).

• Fruitfulness speaks of:

– Spiritual vitality—obedience and love produced by the Spirit (Galatians 5:22-23).

– Missional impact—nations invited to share the harvest (Isaiah 27:6; cf. John 15:5).

– Covenant security—no longer uprooted or burned, but guarded day and night (Isaiah 27:4).

Hosea 14:5-7 pictures the same lush renewal, confirming that God’s ultimate intent is life, not destruction.


summary

Isaiah 27:2 packs a whole storyline into one line: at the divinely appointed future day, God’s people—once barren—will burst into song over His newly flourishing vineyard. The verse announces restoration, calls for worship, and celebrates a protected, productive community, all guaranteed by the faithful Keeper of the vineyard.
