For how great is his goodness, and how great is his beauty! corn shall make the young men cheerful, and new wine the maids. How great is his goodness - In himself and towards them.
And how great is his beauty! - His comeliness, holiness, and purity, put in and upon them.
Corn shall make the young men cheerful - They shall be gladdened and strengthened by plenty of food; and they shall speak aloud of God's mercies in their harvest home.
And new wine the maids - Who shall prepare the wine from an abundant vintage.
Commentary on the Bible, by Adam Clarke [1831].
