Psalms 64:8,9 - Joseph Benson’s Commentary on the Old and New Testaments

They shall make their own tongue, &c. The mischief of their hard speeches, and threats, and crafty counsels against me, shall be turned against themselves. All that see them shall flee away Partly through abhorrence of them, and partly through fear of being involved in their destruction. Some think this was fulfilled in the death of Saul, when not only his army was dispersed, but the inhabitants of the neighbouring country were so terrified with his fall, and with that of his three sons, that they quitted their cities and fled, 1 Samuel 31:7. And all men shall fear A great number of those who shall see this event shall be affected with a holy awe of God upon the consideration of it, and shall fear and tremble because of his judgments; shall fear being found persecutors of God's people. And shall declare the work of God His admirable work of divine wisdom, power, and faithfulness; they shall speak one to another, and to all about them, of the justice of God in punishing persecutors. For they shall wisely consider of his doing Learning wisdom by the folly and misery of these persecutors, and avoiding those evil courses which brought ruin upon them. There is need of consideration and serious thought, rightly to take up such a matter of fact, and need of wisdom to put a true interpretation upon it. What God does is well worth our considering, Ecclesiastes 7:13. But it must be considered wisely, that we do not mistake the design of it, and the instruction it is intended to convey.
