“The wisdom of the prudent is to understand his way: but the folly of fools is deceit.”
King James Version (KJV)
14:8 His way - Consists not in vain speculations, but in a diligent study of his duty, and of the way to eternal happiness. The folly - The wit of ungodly men, which is really their folly, is employed only in finding out ways of deceiving.
