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, Revelation 18:2.
