Why hast thou then broken down her hedges? - Why hast thou dealt with thy people as one would with a vineyard who should break down all its enclosures, and leave it open to wild beasts? The word rendered hedges means wall or enclosure. Compare the notes at Isaiah 5:2.
So that all they which pass by the way - All travelers; or, wild beasts. So that there is nothing to prevent their coming up to the vine and plucking the grapes.
Do pluck her - Pluck, or pick off the grapes; or, if the phrase “all which pass by the way” denotes wild beasts, then the meaning is, that they eat off the leaves and branches of the vine.
