John Gill's Bible Commentary Ver. 5. The righteousness of the perfect shall direct his way , etc.] Or “make [it] plain” f295 ; that is, the righteousness of those who are perfect in Christ, complete in him, perfectly justified by his righteousness; that righteousness makes their way plain; it is the direct way, the highway, the pathway to eternal life and happiness; see ( Proverbs 12:28); but the wicked shall fall by his own wickedness ; or, “in his wickedness” f296 : in his own wicked way, which he has chosen and delights to walk in; he shall stumble therein, and fall into ruin and destruction, into hell and damnation: or by means or because of it he will fall; his wickedness will be the cause of his fall; as it will be the cause of the fall of Babylon, ( Revelation 18:2,5).
Matthew Henry Commentary
