A chiasm is a literary structure where vocabulary of the first section of a passage is repeated in reverse order in the second. The center of the chiasm is typically the climax of the passage. In John 21:1-14 the center and climax is Jesus telling the disciples who were having no success fishing, “Cast the net on the right-hand side of the boat and you will find a catch.” So they cast, and then they were not able to haul it in because of the great number of fish’ (John 21:25-26).
