Resumen:
With elements of the theophanies and the wars of Yahweh from the tribal period, the day of Yahweh is presented by biblical authors as an event in which divine justice is manifested, bringing judgment to the oppressors and salvation to the oppressed. Based on bibliographic and exegetical research, we intend to approach the concept of “the Day of Yahweh” as an intertextual theme that permeates the Old Testament literature. For this, we will analyze the concept of intertextuality in linguistics and applied to biblical studies, mainly from the Old Testament; we will do an exegesis and an intertextual analysis of Zeph 1:7-18 and Joel 2:1-11, two pericopes that bring important details about the day of Yahweh, one pre-exilic, another post-exilic; we will address the origin and development of the day of Yahweh and present the state of the matter and an overview of the concept in the Old Testament. After looking at the diversity of the concept, we will look for common elements of its theology, such as justice and liberation for oppressed and exploited people, shedding light on issues such as Yahweh's warrior character, divine wrath and human oppression
