2 In that
day [yowm] sing [`anah] ye unto her, A
vineyard [kerem] of red wine [chemer][chemed]. KJV-Interlinear
2 In that
day, “A pleasant vineyard, sing of it! ESV
In that day, a phrase that continues to point to the final days and events of history.
A vineyard of red wine, is reflective of the finest of wines, planted in the very best of soils, grown in the very best of climates, tended to with the very best of care.
And so the people of God are planted in faith, in the work of Christ, grown in the climate of doctrine, and cultivated with Gods plan and wisdom and grace. And the result is the production of the finest family, the finest nation, and finest outcome of Gods plan, that will extend into eternity.
And so the song of grace and of salvation and of eternal life, is sung by believers in Christ, in response to the successful result of Gods final judgment against evil.
The choir consists of believers. They sing in response to Gods victory.
