Proverbs 19:3

The foolishness of man perverteth his way ,.... The sinfulness of his heart and nature; the folly which is bound up in it causes him to go astray out of the way in which he should go, or makes things go cross with him; so that the ways he takes do not prosper, nor his schemes succeed; but everything goes against him, and he is brought into straits and difficulties;

and his heart fretteth against the Lord ; laying all the blame on him; and ascribing his ill success, not to his own sin and folly, but to divine Providence, which works against him; and therefore frets and murmurs at him; and, instead of charging his own ways with folly, charges the ways of God with inequality; see Ezekiel 18:25 .
