This paper will trace several potential allusions and echoes to Old Testament and Second Temple texts in Acts 2:1-13. Although scholars have suggested several potential texts from the Hebrew Bible as background for the descent of the Spirit in Acts 2:1-13, no consensus has emerged on what text or texts Luke may have in mind when he describes the descent of the Holy Spirit. After surveying several common suggestions, I will propose one intentional allusion that contributes to Luke’s overall theological agenda.
