Matthew Henry Commentary Proverbs 14:8

"The wisdom of the prudent is to understand his way; But the folly of fools is deceit." — Proverbs 14:8 (ASV)

We are travellers, whose concern is not to spy out wonders, but to get to their journey's end; to understand the rules we are to walk by, also the ends we are to walk toward. The bad man cheats himself and goes on in his mistake.
