Commentators agree that this verse literally prophesies the incredible fertility of the land allotted to the tribe of Judah. The abundance of vineyards and pastures would lead to plentiful wine and milk. Some scholars, like Charles Ellicott, suggest the phrasing means Judah's people would be so healthy that their eyes would be 'brighter than wine' and their teeth 'whiter than milk,' reflecting the prosperity of their homeland.
