Dear children, tell me, what is the Book of Ruth about...?
Ruth, her sister Orpah and her Mother in law Naomi were starving and all their husbands died in the famine.....so they had to find new husbands who would feed them...Boaz owned a huge barley field and he was *gasp* single...and rich! So Naomi, saw the opportunity but as she was too old to marry and bear children, she got Ruth to marry Boaz by tricking him into waking up with her in the barn.
btw Orpah didnt want to go with Naomi and went back to her homeland rather than be in on this husband hunting mission.
