In that day sing ye unto her, A vineyard of red wine.
In that day ... - In that day, when leviathan shall be destroyed, the vineyard (Psalms 80:8), the Church of God, purged of its blemishes, shall be lovely in God's eyes. To bring out this sense the better, Lowth, by changing a Hebrew letter, reads pleasant, lovely ( chemed (H2531)), for 'red wine' ( chemer (H2561)). The Septuagint and Arabic seem to have read so: cf. Amos 5:11. But the Hebrew ought not thus rashly to be changed. Sing - a responsive song х `anuw (H6030)] (Lowth).
Unto her - rather lª-, concerning her (note, Isaiah 5:1); namely, the Jewish state, represented by the vineyard (Maurer).
