His own iniquities shall take the wicked himself; i.e. his manifold sins shall overtake and arrest him. The imagery is borrowed from the snare of the fowler. The emphatic form of the original, "His sins shall overtake him, the impious man," point conclusively to the adulterer.
It is "his" sins that shall overtake him, not those of another, and they shall fall upon his own head; and further, his character is depicted in the condemning clause, "the impious man;" for such he is.
Shall take. The verb lakad is literally "to take or catch animals in a snare or net," properly "to strike with a net." The wicked man becomes entangled and caught in his own sins; he is struck down and captured by them, just as the prey is struck by the snare of the fowler.
The verb is, of course, used metaphorically, as in Job 5:13. The wicked (Hebrew, eth-harasa); in the original introduced as explanatory of the object, "him." And he shall be holden with the cords of his sins.
The Authorized Version follows the LXX. and Vulgate in rendering "his sins," instead of the original "his sin" (khattatho). It is not so much every sin of man which shall hold him, though this is true, as the particular sin treated of in the address, viz.
adultery, which shall do this. The expression, "the cords of his sin" (Hebrew, khavley khattatho), means the cords which his sin weaves around him. Nothing else will be requisite to bind and hold him fast for punishment (cf.
"cords of vanity," in Isaiah 5:18).
