The legal interpretation of the Dead Sea Scrolls has been an important subject in various academic discussions since the scrolls were discovered in Khirbet Qumran near the Dead Sea. Even though we are still uncertain as to the circumstances under which Qumran or the author(s) of each scroll interpreted the scriptural texts, the Qumran scrolls clearly demonstrate a tendency to interpret the biblical texts in a unique manner. In relation to the interpretation of the biblical law, a comparative study of Qumran and rabbinic legal interpretation is often regarded as a significant tool for illuminating a mutual halakhic tradition and reconstructing connections between both methods. This paper compares the legal interpretation in Qumran with the halakhic positions preserved in the rabbinic literature about the biblical commandment on the gift for the poor (Lev 19:9-10), and argues that the Qumran biblical exegesis shows an embryonic trace of the halakhic method similar to what is found in the rabbinic legal interpretations.<BR> For this, I present the legal text from the Scripture, and explain why the text leaves room for interpretation. Then, I provide passages from Qumran related to the biblical text, and compare their interpretations. After introducing the rabbinic interpretation of the same biblical texts and also comparing the Qumran halakhic view with that of the rabbinic literature, I demonstrate both similarities and dissimilarities between the two traditions. While illuminating the motivation behind attempts to interpret the biblical law using unique methods in Qumran and rabbinic halakhah, I finally propose an explanation to clarify why Qumranic halakhah provides the legal interpretation for the measurement of the gift to the poor. The comparative examinations of Qumran literature and the tannaitic writings reconstruct the early aspects of the pre-tannaitic midrash, and provide a clearer understanding about the development of the halakhic methods and the sectarian views on legal interpretations.<BR> In case of measuring the charity to the poor, the Qumranic interpretation sheds light on how the rabbinic halakhah developed its legal interpretations. On the basis of this short research, examinations of early halakhic views provide the chance to look at early exegesis of legal texts and the transformation of the halakhic positions. Thus, it is critical to compare the sectarian halakhah with the rabbinic literature on the creation of the measurement because the sectarian view fills the historical gap between the biblical law and the rabbinic halakhah concerning the development of the interpretation.
