Ruth is a wonderful little book in the Old Testament.  It is connected to the book of Judges both chronologically and thematically. The last two stories in Judges (chapters 17-18, 19-21) occur in and around Behtlehem, as does Ruth.  The great depravity of Israel described in Judges sets the stage for the opening famine in Israel.  Ruth is an amazing woman.  An amazing God guides her every step.
