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 Luke 22:31-62 the center and climax is Jesus praying in the garden of Gethsemane, “Father, if You are willing, remove this cup from Me; yet not My will, but Yours be done” (Luke 22:42).
