Thou hast broken down all his hedges - His walls or defenses; all that he relied on for safety.

Thou hast brought his strongholds to ruin - His towers, fortifications; defenses. The enemy has been suffered to destroy them. They are now heaps of ruins.

Thou hast broken down all his hedges - Thou hart permitted the land to be stripped of all defense; there is not even one strong place in the hands of thy people.

Thou hast broken down all his hedges,.... Round about his vine, the church; see Psalm 80:12. A famous church was raised at Jerusalem, quickly after the death, resurrection, and ascension of Christ, which seemed to be well filled, fenced, and protected; but on a sudden a violent persecution arose, and the members of it were made havoc of, and the ministers of the word were scattered abroad, and which was the breaking down of the hedges; and what was done to the church was taken by Christ as done to himself, as it is here spoken of him; see Acts 8:1, and this might seem contrary to the word and oath of God, that his seed should endure for ever, and his throne as the days of heaven, Psalm 89:29, when the first Christian church was used in this manner; but that providence was overruled, for the spread of the Gospel, and the interest of Christ, in other parts; see Acts 8:4, and so no objection to what is before said:

thou hast brought his strong holds to ruin; the same as before, the church of Christ, which seemed to be so well built and fortified; see Isaiah 26:1.

Thou hast broken down all his hedges; thou hast brought his strong holds to ruin.

40-45. The ruin is depicted under several figures-a vineyard whose broken "hedges," and "strongholds," whose ruins invite spoilers and invaders; a warrior, whose enemies are aided by God, and whose sword's "edge"-literally, "rock" or "strength" (Jos 5:2) is useless; and a youth prematurely old.

89:38-52 Sometimes it is not easy to reconcile God's providences with his promises, yet we are sure that God's works fulfil his word. When the great Anointed One, Christ himself, was upon the cross, God seemed to have cast him off, yet did not make void his covenant, for that was established for ever. The honour of the house of David was lost. Thrones and crowns are often laid in the dust; but there is a crown of glory reserved for Christ's spiritual seed, which fadeth not away. From all this complaint learn what work sin makes with families, noble families, with families in which religion has appeared. They plead with God for mercy. God's unchangeableness and faithfulness assure us that He will not cast off those whom he has chosen and covenanted with. They were reproached for serving him. The scoffers of the latter days, in like manner, reproach the footsteps of the Messiah when they ask, Where is the promise of his coming? 2Pe 3:3,4. The records of the Lord's dealings with the family of David, show us his dealings with his church, and with believers. Their afflictions and distresses may be grievous, but he will not finally cast them off. Self-deceivers abuse this doctrine, and others by a careless walk bring themselves into darkness and distress; yet let the true believer rely on it for encouragement in the path of duty, and in bearing the cross. The psalm ends with praise, even after this sad complaint. Those who give God thanks for what he has done, may give him thanks for what he will do. God will follow those with his mercies, who follow him with praises.
