Charles H. Spurgeon on Psalms 129:4

He hath cut asunder the cords of the wicked. He repeateth the same praise of God in delivering his church from oppression of the enemy, under the similitude of cutting the cords of the plough, which tilleth up another man's field. Whence learn, 1. The enemies of the church do no more regard her than they do the earth under their feet, and do seek to make their own advantage of her, as usurpers use to do in possessing and labouring of another man's field. "The plowers plowed upon my back." 2. The Lord useth to suffer his enemies to break up the fallow ground of his people's proud and stiff hearts with the plough of persecution, and to draw deep and long furrows on them: "They made long their furrows." 3. What the enemies do against the church the Lord maketh use of for maturing the church, which is his field, albeit they intend no good to God's church, yet they serve in God's wisdom to prepare the Lord's people for receiving the seed of God's word; for the similitude speaketh of their tilling of the church, but nothing of their sowing, for that is reserved for the Lord himself, who is owner of the field. 4. When the wicked have performed so much of God's husbandry as he thinketh good to suffer them, then he stoppeth their design, and looseth their plough. "He Hath cut asunder the cords of the wicked." —David Dickson.
