This week's parasha Mattos(Bamidbar 29) opens with a discussion of vows. Some commentaries say it foreshadows the recitation of Kol Nidrei on Yom Kippur. This first specific case of vows in Mattos is by a woman who is getting married and who is bethrothed but still in her father's house. Diverse sources say that it alludes to the simultanous interactions of the feminine aspects of the soul of the Jewish people with its father (HaShem) and with its husband (body, animal soul, negative forces). The soul is bound in a web of obligations. The releasing from vows allows the soul to break out of its confines and to return to its source on Yom Kippur. The three cases: of a woman still in her father's house, one just married but still in her father's house and one whose marriage is completed and solely with her husband represent various scenarios of the complex and competitive relationship of a soul being connected to the world.
