The Shavuot Festival Rituals and its relation with The Ruth Book bring together three key elements about social issues and a threefold category protected by God: Ruth is woman, a foreigner woman, poor and widow. Her character becomes a sort of memory that connect the departure of the enslavement under the Egyptians to a social nature legislation to protect the poor and excluded (Deuteronomy). This research examines the relations between discourse and power in Book of Ruth. Thus, we seek to put in evidence the reality and the meaning of gender experience related to women and social issues showed in that book. Some important concepts are remembered such as laws that deal with poor related social issues, tolerance attitudes and benevolence (Lv 19,9-10; 23,22 e Dt 24,20-22). Ruth’s narrative becomes, therefore, a sort of recovering of social laws that aim to re-establish fair procedures to less-favoured social groups.
