The way of the Lord is strength - In the path of obedience the upright man ever finds his strength renewed; the more he labors the stronger he grows. The same sentiment as that in Isaiah 40:31.
Omit “shall be.” The meaning is: “The Way of Yahweh,” i. e., the Divine Order of the world, has its two sides. It is “strength to the upright, destruction to the workers of iniquity.”
