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 Mark 6:7-13 the center and climax is Jesus telling his disciples, “Any place that does not receive you or listen to you, as you go out from there, shake the dust off the soles of your feet for a testimony against them” (Mark 6:11).
