Ruth is the person after whom the Book of Ruth is named. In the narrative, she is not an Israelite but rather is from Moab; she marries an Israelite. Both her husband and her father-in-law die, and she helps her mother-in-law, Naomi, find protection. The two of them travel to Bethlehem together, where Ruth wins the love of Boaz through her kindness.
She is one of five women mentioned in the genealogy of Jesus found in the Gospel of Matthew, alongside Tamar, Rahab, the "wife of Uriah", and Mary.
