The parallel concentric structures of the Exodus were discovered by applying methods of literary criticism. When dividing the Exodus to 49 pericopes, the longest concentric structure has become, which has 24 pairs of corresponding pericopes. The central pericope of that concentric structure is “Crossing the Red Sea and the pursuers downed” (Ex14:19-31). If dividing the texts to three parts at the pericopes of “Death of the Firstborn” (Ex12:29-36) and “The Israelites Reach Mount Sinai” (Ex19:1-9), each three parts become concentric structure which have 17 pericopes. (“Death of the Firstborn” and “The Israelites Reach Mount Sinai” are included in both front parts and back parts) The contents of three divided texts are the story to get permission of travel, travel from Egypt to Mount Sinai, and events at Mount Sinai. Those three parts of texts corresponds to the division of main narrative structure. Similarly the concentric structures were discovered when text was divided in four parts. Also those structures were discovered when divided in seven parts. The interpretation derived from the central pericopes of those structures and relationships of pericope pairs does not conflict with theological meanings of the Exodus. The positions of those divisions correspond to narrative structure of Exodus. Because of those, the parallel concentric structures seemed to be not incidental but intentional and inevitable structures which were coded by the last editor.
