Intertextuality can be defined with B.J. Oropeza and Steve Moyise, who edited a collective on New Testament intertextuality, as "the study of how a given text is connected with other texts (broadly under­stood) outside of itself and how those texts affect the interpretation of the given text" (2016, xiii-xix). This movement may seem obvious at the core of any biblical exegesis, led according to the canon (literary context) or the historical periods in which the texts were written (historical contexts). But how is this study carried out? What are its specificities? This article aims at answering these two questions. First, it examines the genesis of the notion of intertextuality, from literary theories to biblical sciences. Secondly, it presents an illustration of analysis that serves to consider the results that intertextuality brings to light in the Pauline literature.
