Isaiah 27: 2-3. “In that day sing ye unto her, A vineyard of red wine. I the Lord do keep it; I will water it every moment: lest any hurt it, I will keep it night and day.”
In that day: The Millennium, when Jesus reigns over the whole earth from Jerusalem. Judah will sing a song of God’s vineyard.
Judah is the Vineyard, and God’s anger has passed. These verses describe the tender care He will provide His vineyard during the Millennium. He will make sure it is well-watered, and will protect it night and day.
Verses 4-6 continue this beautiful picture of a restored and redeemed Israel.
