Psalms 35:6

Let their way be dark -Margin, as in Hebrew: “darkness.” That is, let them not be able to see where they go; what danger they incur; what is before them. The idea is that of persons who wander in the night, not knowing what is before them, or what danger may be near. The succession of images and figures here is terrific. The representation is that of persons scattered as the chaff is before the wind; pursued by the angel seeking vengeance; and driven along a dark and slippery path, with no guide, and no knowledge as to the precipices which may be before them, or the enemies that may be pressing upon them.
