John Gill Commentary Psalms 80:12

"Why hast thou broken down its walls, So that all they that pass by the way do pluck it?" — Psalms 80:12 (ASV)

Why hast thou then broken down her hedges
After having done all this for her; which signifies the Lord's removing his presence, power, and protection, from Israel; which were the hedge he set about them, and by which they were secured and defended from their enemies; but these being gone, they became an easy prey to them; see (Job 1:10) (Isaiah 5:2Isaiah 5:5) ,

The hedge about the church and people of God are the angels that encamp about them; salvation, which is as walls and bulwarks to them; and the Lord himself, who is a wall of fire around them; which may be said to be broken down when he withdraws his presence, and does not exert his power in the protection of them; but suffers them to be exposed to the persecutions of men:

so that all they which pass by the way do pluck her ?
the hedge being broken down, all passengers and travellers plucked the fruit of the vine as they passed along, there being noticing to keep them off from it: this may denote the plunder of the Israelites by their enemies, when left of God, they fell into their hands; and the havoc persecutors make of the church of Christ, and their spoiling them of their goods and substance, when they are permitted to do it.
