C. F. Keil and Franz Delitzsch on Proverbs 19:3

Pro 19:3 3 The foolishness of a man overturneth his way,    And his heart is angry against Jahve.

Regarding סלף, vid., at Pro 11:3; also the Arab. signification “to go before” proceeds from the root conception pervertere, for first a letting precede, or preceding (e.g., of the paying before the delivery of that which is paid for: salaf, a pre-numbering, and then also: advanced money), consisting in the reversal of the natural order, is meant. The way is here the way of life, the walking: the folly of a man overturns, i.e., destroys, his life's-course; but although he is himself the fabricator of his own ruin, yet the ill-humour (זעף, aestuare, vid., at Psa 11:6) of his heart turns itself against God, and he blames (lxx essentially correct: αἰτιᾶται) God instead of himself, viz., his own madness, whereby he has turned the grace of God into lasciviousness, cast to the winds the instruction which lay in His providences, and frustrated the will of God desiring his good. A beautiful paraphrase of this parable is found at Sir. 15:11-20; cf. Lam 3:39.
