Charles H. Spurgeon on Psalms 35:8

"Let his net that he hath hid catch himself: into that very destruction let him fall." By giving Ahithophel rope enough, the Lord preserved David from perishing. Who will not admire that Goliath should be slain with his own sword, and that proud Haman should hold Mordecai's stirrup, and be the herald of his honour? The wicked shall be undone by their own doings; all the arrows that they shoot at the righteous shall fall upon their own pates. Maxentius built a false bridge to drown Constantine, but was drowned himself. Henry the Third of France was stabbed in the very same chamber where he had helped to contrive the cruel massacre of the French Protestants. And his brother, Charles the Ninth, who delighted in the blood of the saints, had blood given him to drink, for he was worthy. It is usual with God to take persecutors in the snares and pits that they have laid for his people, as many thousands in this nation have experienced; and though Rome and her confederates are this day a-laying of snares and traps and a-digging of pits for the righteous, who will rather burn than bow to their Baal, yet do but wait and weep, and weep and wait a little, and you shall see that the Lord will take them in the very snares and pits that they have laid and digged for his people. —Condensed from Thomas Brooks.
