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 10:11-16 the center and climax is “He who is a hired hand, and not a shepherd, who is not the owner of the sheep, sees the wolf coming, and leaves the sheep and flees, and the wolf snatches them and scatters them (John 10:12-13).
