The righteousness of the perfect shall direct his way,.... Or "make it plain" (f); 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 Pro 12:28; but the wicked shall fall by his own wickedness; or, "in his wickedness" (g): 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, Rev 18:2. (f) "rectam facit", Cocceius; "complanat viam ejus", Schultens. (g) "in impietate sua", Tigurine version, Montanus, Baynus, Michaelis; "improbitate sua", Junius & Tremellius, Piscator; "in injustitia sua", Cocceius; "in improbitate sua turbulenta", Schultens.
