The Book of Ruth is included in the third division, or the Writings (Ketuvim), of the Hebrew Bible. In most Christian canons it is treated as one of the historical books and placed between Judges and 1 Samuel. It narrates the story of Naomi and her daughter-in-law Ruth, who return to Bethlehem after the deaths of their husbands, where Ruths loyalty to Naomi leads to her marriage to Boaz. Their son Obed becomes the grandfather of King David.
