This thesis approaches the issue of the woman s right to inheritance, through the exegetical, social and theological analysis of Nm 27,1-11 and 36,1-12. Recent exegetical production has made efforts to carry out literary, formal and cultural analyzes in a diachronic perspective of these texts, not always open to research in the synchronic perspective and the analysis of the theological substrate underlying the narratives.The present research recognizes this research desideratum and focuses on synchronic exegesis and theological analysis. In Num 27,1-11, the request of Salfaad s daughters to share in their father s inheritance is narrated, after realizing injustices and gaps in the current legislation, which resulted in the extinction of the name, memory and family heritage. The narrative highlights the acceptance of this claim by YHWH through a legal innovation. In Num 36:1-12, the heads of the families to which the daughters of Salfaad belonged, in turn, record the negative legal consequences of allowing women to inherit, namely, the disintegration and loss of women tribal possessions. This claim, too, is met by YHWH through the requirement of endogamous marriage. Both texts draw attention for registering the emergence of legal innovations from YHWH s decisions that welcome claims for justice and that change customary practices applied throughout the AOP. The sociological approach included an analysis of the practice of the right to inheritance for women in the different societies of the ANE and in the biblical texts. It led to the conclusion that the underlying factor in the juridical permission of women s right to inheritance was the preservation of the patrimony and guarantee of the continuity of agnatic descent. The theological analysis resulted in the conclusion that YHWH s permission for the inheritance of women has as a theological background the promise of the land given to all Israelites and which is theologically anchored in the divine declarations of equality between women and men recorded in the creation narratives, in Gn 1,26-28 and 2,18-23, perspective present in other narratives and in the legislation of the OT.
