Psalms 18:32 - Joseph Benson’s Commentary on the Old and New Testaments

It is God that girdeth me with strength That inspires me with courage, fortitude, and resolution, and gives me strength both of mind and body in battle and war. It is a metaphor taken, either from a military girdle, or a common girdle, wherewith their loose garments were girded about them, and whereby they were rendered fitter for any action. He maketh my way perfect Perfectly plain, and clear from impediments, as pioneers use to prepare the way for the march of an army. Or, the meaning is, he guides me in all my counsels and enterprises, so that I neither miss my way, nor stumble in it, nor come short of my end. “A man's way, in the pursuit of any end, is perfect when the means he uses to attain it are proper and direct, and will finally render him successful in it: and thus God made David's way perfect as he gave him the surest directions how to act, and prospered him in all his measures, to support the dignity of his crown and government.” Chandler.
