Why then have you broken down its walls, so that all who pass along the way pluck its fruit?
PSALM 80 This is a sorrowful prayer, in which the faithful beseech God that he would be graciously pleased to succor his afflicted Church. To excite him the more readily to grant them relief in their distressing circumstances, they compare these circumstances with the condition of the Church in her beginnings, when the Divine favor was conspicuously manifested towards her.

Commenting on Psalm 80:1-19
"Why hast thou then broken down her hedges?" Thou hast withdrawn protection from her after caring for her with all this care; wherefore is this, O Lord? A vine unprotected is exposed to every form of injury; none regard it, all prey upon it: such was Israel when given over to her enemies; such has the church full often been.
The psalmist is here presenting his suit for the Israel of God, and pressing it home at the throne of grace, pleading with God for mercy and grace for them. The church is here represented as a vine (Psa 80:8, Psa 80:14) and a vineyard, Psa 80:15. The root of this vine is Christ, Rom 11:18. The branches are believers, Joh 15:5.
