2 Chronicles 20:1

It came to pass after this also, &c. After Jehoshaphat had been so very well and zealously employed in reforming his kingdom, and providing for the due administration of justice, and the support of religion in it, and when one would have expected to hear of nothing but the peace and prosperity of his reign, he is interrupted in his good work, and brought into great perplexity, through a formidable invasion of his kingdom by several neighbouring nations: this, however, was permitted in order to such a glorious deliverance as was an abundant recompense for the distress he suffered. If we meet with trouble in the way of duty, we may believe it is in order that God may have an occasion of showing us so much the more of his marvellous loving-kindness.
