Why hast thou then broken down her hedges, so that all they which pass by the way do pluck her? Why hast thou broken down -
7. When a vineyard is planted, it is properly fenced to preserve it from being trodden down, or otherwise injured by beasts, and to protect the fruit from being taken by the unprincipled passenger. So God protected Jerusalem and his temple by his own almighty arm; and none of their enemies could molest them as long as they had that protection. As it was now spoiled, it was a proof that that protection had been withdrawn; therefore the psalmist addresses the Lord with, "Why hast thou broken down her hedges?" Had God continued his protection, Jerusalem would not have been destroyed.
