A chiasm is a literary structure where vocabulary of the first section of a passage is repeated in the second. The center of the chiasm is typically the climax of the passage. In Ruth 4:13-17 the center and climax is the blessing of Naomi’s friends who say to her, “May he (her grandson Obed) also be to you a restorer of life and a sustainer of your old age; for your daughter-in-law, who loves you and is better to you than seven sons, has given birth to him” (Ruth 4:15).
