The seminal eschatological discourse of Jesus, present in Mc 13, brings in his body some descriptions of cosmic upheaval, wars and tribulations that can be equally compared to a Hollywood production or literary story of today. This apocalyptic scenario is explored exegetically in this research, taking Mc 13,24-27 as material object. The motivation for choosing the pericope is due to the author s interest in the field that investigates the use of biblical and extra-biblical sources in the evangelical narrative; and it is justified by the incipient academic production that deals with the phenomenon of intertextuality in Marcos. The research problem starts from the following question: what are the contributions of the intertextual analysis in Mc 13,24-27? In view of this questioning, the general objective of the study aims to present the contributions of intertextual analysis based on the source and contextual texts used in Mc 13,24-27. To achieve this objective, the study will have as specific objectives: to describe the literary context of Mc 13; perform the exegetical analysis of the material object by the historical-critical method; investigate hermeneutic assumptions and how biblical exegesis was used in the apostolic period; and, finally, to examine the intertextuality between the source and contextual texts that make up Mc 13,24-27. The work intends to draw attention to the use of the various sources that got or may got in touch with the authors of the New Testament and, in a way, influenced the reinterpretation of the Old Testament.
