Tomorrow starts the festival of Shavuot, a time of spiritual liberation that commemorates the ancient Israelites receiving the Torah at Mount Sinai. The holiday is also linked to the story of Ruth, a Moabite woman, and her relationship with her Israelite mother-in-law, Naomi. As recounted in the Book of Ruth, traditionally read on Shavuot, after Naomi and her daughters-in-law Ruth and Orpah all become widows, Naomi urges the two younger women to leave her and find new husbands.
