Alongside the widespread evidence of alternative traditions in the Bible, in which two or more authors or traditions deal with the same general subjects (e.g., the two accounts of creation in Gen 1–3; the Gospel of John as compared with the first three Gospels), throughout the Bible there are also literary relationships between one book or part of a book and another. Sometimes the authors or editors of one book simply reproduced their sources verbatim; sometimes they were retouched. Often called "synoptic passages," because when viewed together their common elements can be seen, these texts are important in understanding the specific purposes and themes of a writer by analyzing what was included, added, omitted, revised, and rearranged. There follows a listing of the larger synoptic passages throughout the Bible. These texts have a demonstrable literary relationship with each other, either direct, where a source can be identified, or indirect, where a source that no longer survives but must be presumed is quoted at length and verbatim, or with only minor modifications in one or more places.
