The foolishness of man perverteth his way: and his heart fretteth against the LORD.
The foolishness of man perverteth his way: and his heart fretteth against the Lord. It is his own sinful foolishness that leads him in a perverse way, ending in calamity; but instead of laying the blame on himself, he frets against the Lord as the author of his calamities. Just as if one were, through carelessness, to stumble on a stone, and were to blame it for his hurt (1 Peter 2:8).
