This thesis, through an exegetical analysis of Numbers 18,8-24, studies Aaron as a priestly reference who directly receives YHWH s words and conveys them to the children of Israel. Considering that, in the last four decades, few works have been developed on the Book of Numbers (although there has recently been some increase in research on this book), particularly on Numbers 18,8-14, this study contributes with relevance and novelty. The primary goal was to conduct an exegetical analysis of the text, allowing an investigation of Aaron s role as a priestly figure who received YHWH s words concerning the priests and Levites gains from their cultic services. Consequently, it is observed that Numbers 18,8-24 confirms the importance of the priestly tradition in the final composition of the Book of Numbers. While it contains non-priestly materials, this book emphasizes and attests to the fundamental role of priests and Levites in favor of Israel and asserts that they, along with their families, are to receive due compensation. The historical-critical method was employed as an indispensable tool to achieve a deeper and refined understanding of Numbers 18,8-24, but not exclusively, as synchronic methods are also well represented in this work. It is noted that the section is clearly structured, with an introduction, five subsections, and a conclusion, displaying coherence and cohesion, as corroborated by its syntactic and semantic elements. Aaron stands as the central figure and direct recipient of YHWH s word. By classifying Numbers 18,8-24 as priestly Torah, the sacredness of the worship and service performed by the priests and Levites is affirmed, through which Israel is preserved from conflicts and mortal harm (Numbers 16–17).
