Isaiah 27:2,3 - Joseph Benson’s Commentary on the Old and New Testaments

In that day When these powerful enemies shall be destroyed. Sing ye unto her Hebrew, ענו לה, answer ye her, or say ye to her, namely, to the church of God. A vineyard of red wine “Behold a vineyard,” or, “Thou art a vineyard of red wine,” that is, of the choicest and best wine, which in those parts was red, as appears both from the Scriptures and from heathen authors. I the Lord do keep it, &c. I will protect my church from all her enemies, and supply her with my ordinances, word, and Spirit, with all necessary means and helps. “The import of these two verses,” says Lowth, “is, that when the enemies of God's people are destroyed, among other songs and thanksgivings, this acknowledgment shall be made to the praise of God, and of the church which he protects, that as she is fruitful in all good works, so God continually watches over her, and defends her from danger.”
