Job 5:18,19 - Joseph Benson’s Commentary on the Old and New Testaments

For he maketh sore, &c. God's usual method is first to wound and then to heal, first to convince and then to comfort, first to humble and then to exalt. And he never makes a wound too great, too deep, for himself to cure. He will deliver thee If thou seek to him by prayer and repentance; in six troubles In distresses, manifold and repeated. Here he applies himself to Job directly. Yea, in seven there shall no evil touch thee Thou shalt have a good issue out of all thy troubles, though they be both great and many.
