Quick answer
Consequence is described as a pursuer. The verse gives trouble legs and lets it do the chasing.
Read both lines
The image is the chapter's most vivid: evil follows the person who has been generating it, which is a different picture from punishment being dispatched. This is the book's usual account of how outcomes work, the same one 11:19 gave when it said a man pursues evil to his own death, and the reversal here is deliberate. There he chased it; here it chases him. The second line's "repaid" keeps the accounting frame, and the whole verse is a general observation about direction rather than a promise attached to any particular life.
